    • n sulphantimonite A salt of one of the assumed sulpho-acids of trivalent antimony, as Ag3SbS3 (also written 3Ag2S.Sb2S3), the mineral pyrargyrite, or Pb2Sb2S5 (= 2PbS.Sb2S3), the mineral jamesonite. Compounds of this class are common among minerals, the metals usually present being silver, copper, lead, or mercury; similar compounds containing arsenic or bismuth, instead of antimony, are called sulpharsenites and sulphobismuthites respectively. Other related compounds of quintavalent antimony or arsenic are called sulphantimonates and sulpharsenates, as Cu3AsS4 (= 3Cu2S.As2S5), the mineral enargite.
