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 .
