| Popis: | The synthesis and spectroscopic characterization are described of six-coordinated diorganotin(IV) complexes of the type RR′SnX2·L2 and RR′SnL′2 where RR′ = diphenyl, bis(p-tolyl), bis(m-chlorophenyl), bis(p-chlorophenyl), MeEt, Et(n-Pr); X Cl or NCS; L = neutral monodentate oxygen donor (containing , , or grouping) or 1 2 bidentate donor (2,2′-bipyridyl, 4,4′-dimethyl-2,2′-bipyridyl, 1,10-phenanthroline or 3,4,7,8-tetramethyl-1,10-phenanthroline); L′ = 8-quinolinolato or 2-methyl-8-quinolinolato. The spectroscopic (in particular, the 119mSn Mossbauer) data have been used to infer the stereochemistry of the [SnR2] skeleton in these complexes, with confirmation from recent X-ray studies in a few cases. The results indicate that substituents in the carbon- and heteroatom-donor ligands attached to tin have a strong influence on the stereochemical preference for trans- or cis-[SnR2] configurations in the six-coordinated octahedral complexes. |
