摘要：

The planar pentadentate ligand 2,6-diacetylpyridinebis(semicarbazone), DAPSC, was found to combine with SnCl3- dissociated from [Pt(SnCl3)5]3- and form a pentagonal bipyramidal complex of Sn(IV). The complex was characterized by an X-ray crystal structure study. The [Sn(DAPSC]Cl2].2H2O complex crystallized in space group P2(1)/n with four molecules in a unit cell with dimensions a = 9.213(2), b = 13.391(4), c = 16.856(7) angstrom and beta = 95.60(3)-degrees. The R and R(W) values were 0.047 and 0.061, respectively for 2832 reflections. The cation is a slightly distorted pentagonal bipyramid in which the DAPSC ligand forms a pentagonal plane and two chloride ions occupy the axis positions. This is the first example of a metal oxidation taking place in the presence of DAPSC and being stabilized by the ligand.
