Bytízite

This page is currently not sponsored. Click here to sponsor this page.
Formula:
Cu3SbSe3
Colour:
Steel-grey
Lustre:
Metallic
Hardness:
2 - 3
Specific Gravity:
6.324 (Calculated)
Crystal System:
Orthorhombic
Name:
Named after its type locality, the Bytíz deposit, near the village Bytíz.
Known synthetic analogue.
Chemically related to permingeatite and příbramite. The SbSe analogue of wittichenite. Chemically the Se analogue of skinnerite, but this is not a true analogy due to the difference in crystal system.

The crystal structure corresponds to the structure of synthetic Cu3SbSe3 and is structurally related to the high-temperature (>121°C) orthorhombic modification of Cu3SbS3.
