The reaction of dimethyltin(IV)oxide with pyruvic acid thiosemicarbazone (H(2)pt) and subsequent recrystallization from THF leads to the formation two pseudo-polymorphs based on triangular [(CH3)(2)Sn(pt)](3) units; one of them [(CH3)(2)Sn(pt)](3).3THF (1) with tubular cavities while the other [(CH3)(2)Sn(pt)](3).1.5THF (2) is a H-bonded 3D network with truncated tetrahedral cavities.
