Reactions of diorganotin(IV) oxides with isatin 3- and 2-thiosemicarbazones and with isatin 2,3-bis(thiosemicarbazone): influence of diphenyldithiophosphinic acid (isatin = 1H-indole-2,3-dione)

with isatin 2,3-bis(thiosemicarbazone) (H2LL) afforded [SnMe2(LL)]. X-Ray diffraction shows that one TSC chain is bound to the metal through the sulfur atom and the azomethine nitrogen atom, forming a five-membered metallacycle. The other chain co-ordinates through the nitrogen of the hydrazine group following its deprotonation. The co-ordination sphere changes in dmso-d6 solution, in which a molecule
