Bismuth Carbide

Bismuth is one of the post-transition metals (the pnictogens), with chemical properties that are between those of its lighter group 15 sibling antimony and heavier parent lead. It is a brittle, silvery-white, crystalline metal that, with surface oxidation, displays a rosy tinge. It is the most naturally diamagnetic metal and...

Hgcro4 (Hexahydrocomancheite)

Article SummaryThe mineral hgcro4 (hexahydrocomancheite) is a new hg-bearing mineral that forms when 10-4 M HgO and 10-4 M chromic acid are combined under hydrothermal conditions. The crystal structure of a-hgcro4 has been re-determined and consists of distorted [HgO7] pentagonal bipyramids, containing tetrahedral chromate anions. The monohydrate b-hgcro4 adopts the...
