The crystal structure of the selenide-based synthetic sulfosalt CuPbSb3Se6.

ABSTRACT: Single crystals of copper lead tri-anti-mony hexa-selenide, CuPbSb3Se6, were obtained as a minor phase during systematic studies of the formation conditions of selenide-based sulfosalts. The crystal structure is an unusual representative of the family of sulfosalts. Instead of the expected galena-like slabs with octa-hedral coordination, it features mono and double-capped trigonal-prismatic (Pb), square-pyramidal (Sb) and trigonal-bipyramidal (Cu) coordination. All metal positions are occupationally and/or positionally disordered.
