Copper sulfides describe a family of chemical compounds and minerals with the formula CuxSy. Both minerals and synthetic materials comprise these compounds. Some copper sulfides are economically important ores. Prominent copper sulfide minerals include Cu2S (chalcocite) and CuS (covellite). In the … See more The naturally occurring mineral binary compounds of copper and sulfur are listed below. Investigations of covellite (CuS) indicate that there are other metastable Cu-S phases still to be fully characterised. • See more The bonding in copper sulfides cannot be correctly described in terms of a simple oxidation state formalism because the Cu-S bonds are somewhat covalent rather than ionic in character, and have a high degree of delocalization resulting in complicated electronic band structures See more Copper sulfides can be classified into three groups: Monosulfides, 1.6 ≤ Cu/S ≤ 2: their crystal structures consist of isolated sulfide anions that are closely related to either hcp or fcc lattices, without any direct S-S bonds. The copper ions are … See more • Copper(I) sulfide • Copper(II) sulfide See more • Copper sulfides mineral information and data See more
