| Abstract: | The hitherto controversial valence states of nickel and tin in the ternary chalcogenide Ni3Sn2S2 (see structure) have been determined by photoelectron and Mössbauer spectroscopy (61Ni, 119Sn). Results from band structure calculations confirmed that this shandite phase is a metal and that the approximate distribution of the valence electrons is (Ni0)3(Sn(1)II)(Sn(2)II)(SII−)2. |
