Mohite

Formula:
Cu2SnS3
Colour:
Gray
Lustre:
Metallic
Hardness:
4
Specific Gravity:
4.86 (Calculated)
Crystal System:
Monoclinic
Name:
Named in 1982 by V. A. Kovalenka, V. S. Malov, T. L. Evstigneeva, and L. S. Vyals in honor of Günter Harald Moh (1929–1994), University of Heidelberg, Germany, who first synthesised the compound and had done numerous studies on sulphide systems.
Synthetic Cu2SnS3 apparently has two low-temperature polymorphs: a monoclinic one (Onoda et al., 2000; probably identical to mohite) and a (disordered) stannite-type structure (Chen et al., 1998). A phase transition occurs 780°C, leading to a sphalerite-type structure.
