Kenorozhdestvenskayaite-(Fe)

A valid IMA mineral species
This page is currently not sponsored. Click here to sponsor this page.
Formula:
[Ag6]4+(Ag4Fe2+2)Sb4S12◻
Ag in the M2 site consists of a [Ag6]4+ cluster that presumably exhibits metal-metal bonding; the "missing" M2 charge is compensated by a vacancy in the S2 site; thus, there are only 12 S atoms per formula unit, not 13.

(Ag4+)6 = [(Ag+)2/3(Ag0)1/3)]6
Colour:
black
Lustre:
Metallic
Specific Gravity:
5.329 (Calculated)
Crystal System:
Isometric
Name:
For Russian mineralogist Irina Rozhdestvenskaya and its iron content and keno indicates vacancy at the S(2) site.
This page provides mineralogical data about Kenorozhdestvenskayaite-(Fe).
