About Samraite
Formula:
Ni2P2O7
Crystal System:
Monoclinic
Known synthetic analogue. A chemical (but not truly analogous) counterpart of nabateaite (a Fe-dominant counterpart). Chemically somewhat similar to lisanite and the tetraphosphate species phosphocyclite-(Ni).
The most simple Ni phosphate among minerals (alongside with phosphocyclite-(Ni)).
The most simple Ni phosphate among minerals (alongside with phosphocyclite-(Ni)).
