Abstract

The reaction of PbPh2Cl2 with two dissymmetric thiosemicarbazone ligands containing diacetyl 4-methyl-3-thiosemicarbazone and hydrazonepyridine or hydrazonequinoline arms led to four new mononuclear complexes, [PbPh2(L)] (1 and 3) and [PbPh2Cl(HL)] (2 and 4). Reactions with the hydrazonequinoline ligand strongly depend on the reaction conditions and several unexpected compounds were isolated. At room temperature, in addition to complex 4, the polymeric compound [PbPh2Cl2CH3OH]n (5) was isolated, whereas under heating at reflux a symmetrization took place and a polymer containing diacetyl bis(4-methyl-3-thiosemicarbazone), [PbPh2Cl2(H2ATSM)]n (6) was obtained. When PbPh2Cl2 was heated at reflux in wet dichloromethane with LiOH·H2O, the tetranuclear organoplumboxane [Pb4Ph8Cl4O2] (7) was isolated, which, to the best of our knowledge, is the first organoplumboxane to be crystallographically characterized. All the compounds were thoroughly characterized, including by 207Pb NMR and single-crystal XRD. In addition, the hydrazonequinoline ligand has demonstrated its potential application as a chromophoric probe in the visible region for organolead(IV) species.
