About Puninite
Yurii O. Punin
Formula:
Na2Cu3O(SO4)3

Member of:
Name:
Named in honor of Yurii Olegovich Punin (Юрий Олегович Пунин) (1941–2014), Russian crystallographer at the Institute of Earth Sciences, Department of Crystallography, St. Petersburg State University, Russia. He was an expert on the growth of crystals and genetic mineralogy.
The first Na-dominant Cu oxosulphate of the locality; chemically somewhat resembling saranchinaite. Compare also euchlorine, wulffite, and parawulffite.
May be a representative of "euchlorine group"; the unit-cell parameter a of this group is very sensitive to the K/Na ratio.
Structurally related to euchlorine and fedotovite. As in the case of all other Cu oxysulphate minerals, the structure organizanion may be described via a “host–guest” principle. It consists, i.a., of [O2Cu6]8+ dimers. The dimers contact with four sulphate tetrahedra in a "face-to-face"; the remaining sulphate groups link the dimers in two dimensions.
