Formula:
[Cu5O2](AsO4)(VO4) · (Cu,K,Pb,Rb,Cs,)Cl
The original paper reports the following formula: [Cu5O2](AsO4)(VO4)·(Cu0.5□0.5)Cl
Colour:
Dark red
Lustre:
Adamantine
Specific Gravity:
4.887 (Calculated)
Crystal System:
Monoclinic
Name:
Named for the Aleuts, the ethnic group who are the original inhabitants living on the Commander Islands, Aleutsky District, Kamchatka Krai.
New structure type. However, it may be compared to averievite which was once reported to be Cu5O2(VO4)2·CuCl2·(Cs, K, Rb)Cl. Also somewhat comparable with piypite.
An example of natural salt-inclusion compound. The structure is a derivative of a kagome-type net. Unique among both natural and synthetic arsenates and vanadates in having these two tetrahedral groups distributed over separate structural positions. The oxygen-centered bands in the structure are also unique.
