About MambertiiteHide

Formula:
BiMo5+2.80O8(OH)
Colour:
Pale yellow
Lustre:
Adamantine
Crystal System:
Triclinic
Name:
Its name honors the Italian mineral collector Marzio Mamberti (b. 1959) for his contribution to the knowledge of the Sardinian mineralogy.
Structurally related to gelosaite. Characterizes in the presence of pentavalent molybdeum. The fourth recognized Bi-Mo mineral.

Structure details/elements:
- [8]Bi-centred polyhedra
- five independent Mo-centred octahedra, only two of these are fully occupied
- two kinds of (101) layers alternating along [101]*:
* comprising Bi-centered polyhedra and two partially occupied Mo4 and Mo5 sites,
* comprising zigzag chains along c with the fully occupied Mo1 and Mo2 sites and the partially occupied Mo3 site.
