ABSTRACT

A fascinating ligand, 4-formylpiperazinium 4-formylpiperazine-1-carbodithioate (L-salt) has been reacted with two electronically and sterically different trimethyltin(IV) chloride and triphenyltin(IV) chloride. The complexes 1 and 2 were characterized by elemental analysis, spectroscopic techniques, and X-ray single crystal analysis. The latter technique confirmed the polymeric and monomeric nature of 1 and 2, respectively. Both 1 and 2 showed intriguing molecular packing properties in the solid state. However, the packing of 1 is more interesting and unique where one-dimensional polymer chains self assemble in two-over-two saltire-shaped fashion to provide an overall multilayered structure. The different behavior of L toward two different tin(IV) compounds can be attributed to different electronic and steric environments around metal center.
