Michael Lappert
Michael Franz Lappert (31 December 1928 – 28 March 2014) was a Czech-born British inorganic chemist. Mainly located at the University of Sussex, he was recognized for contributions to organometallic complexes. Early life and education Lappert was born in Czechoslovakia and came to the UK as a ''Kindertransport'' refugee. He received his PhD in 1951 at the Northern Polytechnic, London. Career and research His areas of research often included studies on low coordination numbers and metal amido complexes Metal amides (systematic name metal azanides) are a class of coordination compounds composed of a metal center with amide ligands of the form NR2−.

University Of North London
The University of North London (UNL) was a university in London, England, formed from the Polytechnic of North London (PNL) in 1992 when that institution was granted university status. PNL, in turn, had been formed by the amalgamation of the Northern Polytechnic and North-Western Polytechnic in 1971. In 1996, the university celebrated its centenary, dating from the year of the Northern Polytechnic's founding. UNL existed until 2002, when it merged with London Guildhall University to form London Metropolitan University. Its former premises now form the University's north campus, on Holloway Road and Highbury Grove, London Borough of Islington, Islington. Structure Under the board of governors, the university was arranged into four faculties each led by a dean and pro vice-chancellor:— ;Faculty of Environmental and Social Studies: *School of Law, Governance and Information Management (formerly schools of Law and of Information and Communications Studies) *School of Social Scien ...

Inorganic Chemists
In chemistry, an inorganic compound is typically a chemical compound that lacks carbon–hydrogen bonds, that is, a compound that is not an organic compound. The study of inorganic compounds is a subfield of chemistry known as ''inorganic chemistry''. Inorganic compounds comprise most of the Earth's crust, although the compositions of the deep mantle remain active areas of investigation. Some simple carbon compounds are often considered inorganic. Examples include the allotropes of carbon (graphite, diamond, buckminsterfullerene, etc.), carbon monoxide, carbon dioxide, carbides, and the following salts of inorganic anions: carbonates, cyanides, cyanates, and thiocyanates. Many of these are normal parts of mostly organic systems, including organisms; describing a chemical as inorganic does not necessarily mean that it does not occur within living things. History Friedrich Wöhler's conversion of ammonium cyanate into urea in 1828 is often cited as the starting point of modern ...

Metal Amido Complexes
Metal amides (systematic name metal azanides) are a class of coordination compounds composed of a metal center with amide ligands of the form NR2−. Amide ligands have two electron pairs available for bonding. In principle, they can be terminal or bridging. In these two examples, the dimethylamido ligands are both bridging and terminal: File:Tris(dimethylamino)aluminium dimer.png, Tris(dimethylamino)aluminium dimer File:Tris(dimethylamino)gallium dimer.png, Tris(dimethylamino)gallium dimer File:Ti(NMe2)4.png, Tetrakis(dimethylamino)titanium File:Ta(NMe2)5.png, Pentakis(dimethylamido)tantalum In practice, bulky amide ligands have a lesser tendency to bridge. Amide ligands may participate in metal-ligand π-bonding giving a complex with the metal center being co-planar with the nitrogen and substituents. Metal bis(trimethylsilyl)amides form a significant subcategory of metal amide compounds. These compounds tend to be discrete and soluble in organic solvents. Alkali metal am ...

Kindertransport
The ''Kindertransport'' (German for "children's transport") was an organised rescue effort of children (but not their parents) from Nazi-controlled territory that took place during the nine months prior to the outbreak of the Second World War. The United Kingdom took in nearly 10,000 predominantly Jewish children from Germany, Austria, Czechoslovakia, Poland, and the Free City of Danzig. The children were placed in British foster homes, hostels, schools, and farms. Often they were the only members of their families who survived the Holocaust. The programme was supported, publicised, and encouraged by the British government. Importantly the British government waived the visa immigration requirements that were not within the ability of the British Jewish community to fulfil. The British government put no number limit on the programme – it was the start of the Second World War that brought it to an end, at which time about 10,000 kindertransport children had been brought to ...

East Sussex
East Sussex is a ceremonial and non-metropolitan county in South East England on the English Channel coast. It is bordered by Kent to the north and east, West Sussex to the west, and Surrey to the north-west. The largest settlement in East Sussex is the city of Brighton and Hove. History East Sussex is part of the historic county of Sussex, which has its roots in the ancient kingdom of the South Saxons, who established themselves there in the 5th century AD, after the departure of the Romans. Archaeological remains are plentiful, especially in the upland areas. The area's position on the coast has also meant that there were many invaders, including the Romans and later the Normans. Earlier industries have included fishing, iron-making, and the wool trade, all of which have declined, or been lost completely. Governance Sussex was historically sub-divided into six rapes. From the 12th century the three eastern rapes together and the three western rapes together had separ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Organometallic Complex
Organometallic chemistry is the study of organometallic compounds, chemical compounds containing at least one chemical bond between a carbon atom of an organic molecule and a metal, including alkali, alkaline earth, and transition metals, and sometimes broadened to include metalloids like boron, silicon, and selenium, as well. Aside from bonds to organyl fragments or molecules, bonds to 'inorganic' carbon, like carbon monoxide (metal carbonyls), cyanide, or carbide, are generally considered to be organometallic as well. Some related compounds such as transition metal hydrides and metal phosphine complexes are often included in discussions of organometallic compounds, though strictly speaking, they are not necessarily organometallic. The related but distinct term " metalorganic compound" refers to metal-containing compounds lacking direct metal-carbon bonds but which contain organic ligands. Metal β-diketonates, alkoxides, dialkylamides, and metal phosphine complexes are repre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inorganic Chemist
Inorganic chemistry deals with synthesis and behavior of inorganic and organometallic compounds. This field covers chemical compounds that are not carbon-based, which are the subjects of organic chemistry. The distinction between the two disciplines is far from absolute, as there is much overlap in the subdiscipline of organometallic chemistry. It has applications in every aspect of the chemical industry, including catalysis, materials science, pigments, surfactants, coatings, medications, fuels, and agriculture. Key concepts Many inorganic compounds are ionic compounds, consisting of cations and anions joined by ionic bonding. Examples of salts (which are ionic compounds) are magnesium chloride MgCl2, which consists of magnesium cations Mg2+ and chloride anions Cl−; or sodium oxide Na2O, which consists of sodium cations Na+ and oxide anions O2−. In any salt, the proportions of the ions are such that the electric charges cancel out, so that the bulk compound is electricall ...
