摘要

The reactions of the ligands 2,6-diacetylpyridine bis(S-methyldithiocarbazate)] (H2dapmdtc) and 2,6-diacetylpyridine bis(S-benzyldithiocarbazate)] (H2dapbdtc) with R_(4-m)SnCl_m (R = Me, ~nBu, Ph; and m = 2) led to the formation of six seven-coordinate diorganotin(IV) complexes, which were studied by microanalysis, i.r., n.m.r (~1H, ~(119)Sn) and Mossbauer spectroscopies. The X-ray structures determination of complexes [Me2Sn(dapmdtc)], [Me2Sn(dapbdtc)] and [Ph2Sn(dapbdtc)] revealed the presence of neutral seven-coordinated complexes. The structures consist of monomeric units in which the Sn(IV) atom exhibits distorted pentagonal bipyramidal (PBP) geometry, with the S,N,N,N,S-donor systems of the ligands lying in the equatorial plane and organic groups in the apical positions. A correlation between Mossbauer and X-ray data based on the point-charge model is discussed.
