Formula:
[Hg2]2+Hg2+[AsO4]Cl
formula may instead be [Hg3]4+[AsO4]Cl, where the three Hg atoms occur as a polyatomic cluster.
Lustre:
Adamantine, Vitreous
Specific Gravity:
8.64 - 8.82
Name:
Named in honor of Valery Alekseevich Kuznetsov (Валерий Алексеевич Кузнецов) (12 April 1906, Nikolsk, Vologda province, Russian Empire - 4 August 1985, Novosibirsk, USSR), Russian geologist. He was an expert in magmatism and endogenous ore formation (mercury and non-ferrous metals) and discovered the Aktash and Peza mercury deposits (Gorny Altai).
According to Borisov et al. (2003) it might be possible that kuzetsovite - as terlinguaite - contains the [Hg3]4+ polycation.
