The chelating properties of the pentadentate ligand 2,6-diacetylpyridine bis(thiosemicarbazone) hydrochloride, H(2)daptsc.HCl, have been investigated in a new organotin complex, [PhSnPh(Hdaptsc)]Cl or [Sn(C6H5)(2)(C11H14N7S2)]Cl}. The structure determination revealed a monocationic complex consisting of a heptacoordinated Sn-IV in a distorted pentagonaI-bipyramidal geometry, with the thiosemicarbazone derivative acting as a pentadentate species at the equatorial plane and two phenyl groups at trans positions. The chloride acts as a counterion. Sn-119 Mossbauer measurements showed that the isomer shift and the quadrupole splitting are consistent with structural interpretation.
