Tetrasulfur Tetranitride
Tetrasulfur tetranitride is an inorganic compound with the formula . This gold-poppy coloured solid is the most important binary sulfur nitride, which are compounds that contain only the elements sulfur and nitrogen. It is a precursor to many S-N compounds and has attracted wide interest for its unusual structure and bonding. Nitrogen and sulfur have similar electronegativities. When the properties of atoms are so highly similar, they often form extensive families of covalently bonded structures and compounds. Indeed, a large number of S-N and S-NH compounds are known with as their parent. Structure adopts an unusual “extreme cradle” structure, with D2d point group symmetry. It can be viewed as a derivative of a (hypothetical) eight-membered ring (or more simply a 'deformed' eight-membered ring) of alternating sulfur and nitrogen atoms. The pairs of sulfur atoms across the ring are separated by 2.586 Å, resulting in a cage-like structure as determined by single crystal X- ...

Main-group Element
In chemistry and atomic physics, the main group is the group of elements (sometimes called the representative elements) whose lightest members are represented by helium, lithium, beryllium, boron, carbon, nitrogen, oxygen, and fluorine as arranged in the periodic table of the elements. The main group includes the elements (except hydrogen, which is sometimes not included) in groups 1 and 2 (s-block), and groups 13 to 18 (p-block). The s-block elements are primarily characterised by one main oxidation state, and the p-block elements, when they have multiple oxidation states, often have common oxidation states separated by two units. Main-group elements (with some of the lighter transition metals) are the most abundant elements on Earth, in the Solar System, and in the universe. Group 12 elements are often considered to be transition metals; however, zinc (Zn), cadmium (Cd), and mercury (Hg) share some properties of both groups, and some scientists believe they should be included i ...

Bayer AG
Bayer AG (, commonly pronounced ; ) is a German multinational pharmaceutical and biotechnology company and one of the largest pharmaceutical companies in the world. Headquartered in Leverkusen, Bayer's areas of business include pharmaceuticals; consumer healthcare products, agricultural chemicals, seeds and biotechnology products. The company is a component of the Euro Stoxx 50 stock market index. Bayer was founded in 1863 in Barmen as a partnership between dye salesman Friedrich Bayer and dyer Friedrich Weskott. As was common in this era, the company was established as a dyestuffs producer. The versatility of aniline chemistry led Bayer to expand their business into other areas, and in 1899 Bayer launched the compound acetylsalicylic acid under the trademarked name Aspirin. In 1904 Bayer received a trademark for the "Bayer Cross" logo, which was subsequently stamped onto each aspirin tablet, creating an iconic product that is still sold by Bayer.

Society Of German Chemists
The German Chemical Society (German: ', GDCh) is a learned society and professional association founded in 1949 to represent the interests of German chemists in local, national and international contexts. GDCh "brings together people working in chemistry and the molecular sciences and supports their striving for positive, sustainable scientific advance – for the good of humankind and the environment, and a future worth living for."Gesellschaft Deutscher Chemiker (GDCh)About us, Mission Statement and History/ref> History The earliest precursor of today's GDCh was the German Chemical Society (', DChG). Adolf von Baeyer was prominent among the German chemists who established DChG in 1867; and August Wilhelm von Hofmann was the first president. This society was modeled after the British Chemical Society, which was the precursor of the Royal Society of Chemistry. Like its British counterpart, DChG sought to foster the communication of new ideas and facts throughout Germany and across ...

Horst Mahler
Horst Mahler (born 23 January 1936) is a German former lawyer and political activist. He once was a far-left militant and a founding member of the Red Army Faction who later became a Maoist, before switching to neo-Nazism. Between 2000 and 2003, he was a member of the far-right National Democratic Party of Germany. Since 2003, he has repeatedly been convicted of ''Volksverhetzung'' ("incitement of popular hatred") and Holocaust denial, and he served much of a twelve-year prison sentence. In April 2017, Mahler was ordered back to prison for a further three and a half years. On 18 April 2017, he fled the Federal Republic of Germany, hoping to avoid execution of the sentence. His attempt to receive political asylum in Hungary was rejected, and he was deported back to Germany, where he was arrested and put back in jail to finish serving his sentence. Early life and career Mahler was born at Haynau in Silesia on 23 January 1936, the son of a dentist. In February 1945, as the end ...

German Student Movement
The West German student movement or sometimes called the 1968 movement in West Germany was a social movement that consisted of mass student protests in West Germany in 1968; participants in the movement would later come to be known as 68ers. The movement was characterized by the protesting students' rejection of traditionalism and of German political authority which included many former Nazi officials. Student unrest had started in 1967 when student Benno Ohnesorg was shot by a policeman during a protest against the visit of Mohammad Reza Pahlavi, the Shah of Iran. The movement is considered to have formally started after the attempted assassination of student activist leader Rudi Dutschke, which sparked various protests across West Germany and gave rise to the public opposition. The movement would create lasting changes in German culture. Background Political atmosphere The ''Spiegel'' affair of 1962, in which journalists were arrested and detained for reporting on the ...
