Ammineite

This page is currently not sponsored. Click here to sponsor this page.
Formula:
[CuCl2(NH3)2]
Crystal System:
Orthorhombic
Name:
Named in allusion to being the first mineral species containing an ammine (NH3) complex in the composition.
Not to be confused with amminite.

First recognized mineral with ammine (NH3) group; one of four currently known NH3-bearing minerals, by chanabayaite, joanneumite and shilovite. Elements in ammineite may also be found in buttgenbachite, but its chemical systematics is different.
