Khinite

This page is currently not sponsored. Click here to sponsor this page.
Formula:
Pb2+Cu32+[Te6+O6](OH)2
System:
Orthorhombic
Colour:
Dark green to bottle ...
Hardness:
3
Name:
For Basaw Khin, Phelps Dodge mineralogist
Two polytypes are known, khinite-4O (orthorhombic) and khinite-3T (trigonal). The two polytypes have different stackings of otherwise identical layers of composition [Cu3(TeO6)(OH)2]2-, with Pb2+ cations between the layers.

4 : OXIDES (Hydroxides, V[5,6] vanadates, arsenites, antimonites, bismuthites, sulfites, selenites, tellurites, iodates)
F : Hydroxides (without V or U)
D : Hydroxides with OH, without H2O; chains of edge-sharing octahedra
