Carbonate Chloride
The carbonate chlorides are double salts containing both carbonate and chloride anions. Quite a few minerals are known. Several artificial compounds have been made. Some complexes have both carbonate and chloride ligands. They are part of the family of halocarbonates. In turn these halocarbonates are a part of mixed anion materials. The carbonate chlorides do not have a bond from chlorine to carbon, however "chlorocarbonate" has also been used to refer to the chloroformates which contain the group ClC(O)O-. Formation Natural Scapolite is produced in nature by metasomatism, where hot high pressure water solutions of carbon dioxide and sodium chloride modify plagioclase. Chloroartinite is found in Sorel cements exposed to air. Minerals In 2016 27 chloride containing carbonate minerals were known. Artificial Complexes The " lanthaballs" are lanthanoid atom clusters held together by carbonate and other ligands. They can form chlorides. Examples are a13(ccnm)6(CO3)14(H2O)6 ...

Double Salts
A double salt is a salt that contains two or more different cations or anions. Examples of double salts include alums (with the general formula ) and Tutton's salts (with the general formula ). Other examples include potassium sodium tartrate, ammonium iron(II) sulfate (Mohr's salt), potassium uranyl sulfate (used to discover radioactivity) and bromlite . The fluorocarbonates contain fluoride and carbonate anions. Many coordination complexes form double salts. Double salts should not be confused with complexes. Double salts only exist in the solid. When dissolved in water, a double salt acts as a mixture of the two separate salts: it completely dissociates into simple ions while a hexaaquo complex does not; the complex ion remains unchanged. Similarly, potassium hexaiodoytterbate(II) is a complex salt and contains the discrete hexaiodoytterbate(II) ion , which remains intact in aqueous solutions. In many cases, the complex ion is indicated by square brackets " . Double salts are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reederite-(Y)
Reederite-(Y) is a rare mineral with the formula . It is the only known mineral with fluorosulfate ( fluorosulfonate). "REE" in the formula stands for rare earth elements other than yttrium, that is mostly cerium, with traces of neodymium, dysprosium, lanthanum and erbium. The formula also includes a Levinson suffix "-(Y)" pointing to the dominance of yttrium at the corresponding site. Reederite-(Y) crystallizes in the hexagonal In geometry, a hexagon (from Greek , , meaning "six", and , , meaning "corner, angle") is a six-sided polygon. The total of the internal angles of any simple (non-self-intersecting) hexagon is 720°.

Phosgenite
Phosgenite is a rare mineral consisting of lead chlorocarbonate, (PbCl)2CO3. The tetragonal crystals are prismatic or tabular in habit: they are usually colorless and transparent, and have a brilliant adamantine lustre. Sometimes the crystals have a curious helical twist about the tetrad or principal axis. The hardness is 3 and the specific gravity 6.3. The mineral is rather sectile, and consequently was earlier known as corneous lead, (German ''Hornblei''). Name and occurrence The name phosgenite was given by August Breithaupt in 1820, from phosgene, carbon oxychloride, because the mineral contains the elements carbon, oxygen and chlorine. It was found associated with anglesite and matlockite in cavities within altered galena in a lead mine at Cromford, near Matlock: hence its common name cromfordite.

Northupite
Northupite is an uncommon evaporite mineral, with the chemical formula Na3Mg(CO3)2Cl. It occurs as colourless to dark grey or brown octahedral crystals and as globular masses. In synthetic material it forms a series with tychite (Na6Mg2(CO3)4SO4). It was discovered in 1895 at Searles Lake, San Bernardino County, California by C. H. Northup (born 1861) from San Jose, California, for whom Northupite is named. It occurs associated with tychite, pirssonite at Searles Lake and with shortite, trona, pirssonite, gaylussite, labuntsovite, searlesite, norsethite, loughlinite, pyrite and quartz in the Green River Formation of Wyoming Wyoming () is a U.S. state, state in the Mountain states, Mountain West subregion of the Western United States.

Marialite
Marialite is a silicate mineral with a chemical formula of if a pure endmember or with increasing meionite content. Marialite is a member of the scapolite group and a solid solution exists between marialite and meionite, the calcium endmember. It is a rare mineral usually used as a collector's stone. Crystallography Marialite has tetragonal crystallography and a 4/m crystal class. It has a 4 fold rotation with 90° mirror planes. Crystals are usually prismatic with prominent forms of prisms and dipyramids.Johnsen, O. (2000) Photographic Guide to Minerals of the World. 439 p. Oxford University Press, Great Clarendon Street, Oxford Marialite belongs to a uniaxial negative optical class which means it has one circular section and a principal section shaped like an oblate sphenoid. Discovery and occurrence Marialite was first described in 1866 for an occurrence in the Phlegrean Volcanic complex, Campania, Italy. It was named by German mineralogist Gerhard vom Rath for his wife, M ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kampfite
Kampfite is a rare barium silicate–carbonate– halide mineral with the chemical formula . Discovered in 1964 and described in 2001, it is named after Anthony R. Kampf. The mineral is known only from Fresno County, California. Description Kampfite is translucent and light blue-gray in color. Specimens occur as irregular masses up to in size. Composition and structure When first described, the formula was identified as . Subsequent work on analyzing the crystal structure led to a revised formula of . The structural noted in the original description was not found in the later work. The structure consists of double layers of tetrahedra connected by barium-containing polyhedra. It is this layering which causes kampfite's one perfect cleavage. Kampfite shares chemical and structural similarities with cymrite. , it is the only known barium silicate carbonate aside from fencooperite. Occurrence Kampfite has been found in association with celsian, fresnoite, macdonaldite, p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
