Borate sulfides are chemical mixed anion compounds that contain any kind of borate and sulfide ions. They are distinct from thioborates in which sulfur atoms replace oxygen in borates. There are also analogous borate selenides, with selenium ions instead of sulfur.

BH3·THF requires sodium borohydride to inhibit reduction of THF to tributyl borate (B(OCH2CH2CH2CH3)3). BMS is soluble in most aprotic solvents. Although usually...
The Borate Minerals are minerals which contain a borate anion group. The borate (BO3) units may be polymerised similar to the SiO4 unit of the silicate...
The sulfide minerals are a class of minerals containing sulfide (S2−) or disulfide (S2−2) as the major anion. Some sulfide minerals are economically important...
