Formula:
Pd8(As,Sn,Sb)3
From the original paper: Pd2+-x(As,Sn,Sb)
Crystal System:
Orthorhombic
Compositionally but not structurally similar to arsenopalladinite. Possibly polymorphous with arsenopalladinite and stillwaterite.
Possibly identical with palarstanide: very similar PXRD.
From Talnakh deposit. As rounded, elongated grains and hexagonal euhedral
crystals, 5-50 microns (mean: l5 microns). Associated minerals: chalcopyrite, galena, electrum, Ag-Au alloys, polarite, silicates, sphalerite, sperrylite, talnakhite, other PGM.
