Moessbauer Effect of /sup 119/Sn in the SnS-BaS and SnS-Tl/sub 2/S systems (in French)

Journal Article · · J. Solid State Chem.; (United States)
Tin-119 Moessbauer spectra have been recorded at liquid nitrogen and room temperatures for ternary sulfides isolated from the system SnS-BaS and SnS-Tl/sub 2/S. The chemical isomer shifts observed (2.8-3.4 mm/sec relative to BaSnO/sub 3/ K) are characteristic of divalent tin compounds. The data are consistent with the known structures of these compounds and are discussed with regard to the stereochemical activity of the tin(II) lone pair of electrons. For Tl/sub 2/Sn/sub 2/S/sub 3/ and Tl/sub 4/SnS/sub 3/ the Moessbauer parameters are interpreted in terms of direct population of conductance bands by nonbonding electron pairs.
