title: The Valence States of Nickel, Tin, and Sulfur in the Ternary Chalcogenide Ni(3)Sn(2)S(2)-XPS, (61)Ni and (119)Sn Mössbauer Investigations, and Band Structure Calculations.
abstract: The hitherto controversial valence states of nickel and tin in the ternary chalcogenide Ni(3)Sn(2)S(2) (see structure) have been determined by photoelectron and Mössbauer spectroscopy ((61)Ni, (119)Sn). Results from band structure calculations confirmed that this shandite phase is a metal and that the approximate distribution of the valence electrons is (Ni(0))(3)(Sn(1)(II))(Sn(2)(II))(S(II-))(2).
