Tellurocanfieldite

This page is currently not sponsored. Click here to sponsor this page.
Formula:
Ag8Sn(S,Te)6
System:
Orthorhombic
A variety of Canfieldite

Originally approved but approval has subsequently been withdrawn because a subsequent single-crystal structural analysis has shown that Te is disordered over the three sulphur sites and thus the material is in fact Te-rich canfieldite.
