Abstract

Reactions of imidazolidine-2-thione (Imt), 1,3-diazinane-2-thione (Diaz) and 1,3-diazipane-2-thione (Diap) with Cd(SeCN)2 in acetonitrile resulted in the formation of 2:1 tetrahedral complexes. Both solid state and solution NMR, confirm the exocyclic thione atom to be the donor in all cases. 113Cd shielding tensors and anisotropies were calculated from the solid-state NMR spectra. Based on the solid NMR data, a distorted tetrahedral dispositions of ligands around cadmium is proposed for the Imt complex. However, when the Imt ligand is substituted with one or two R groups (where R=Me, Et or i-Pr) forming RImt or R2Imt, a five coordinate complex with polymeric structure [(RImt)Cd(SeCN)2]∞ or [(R2Imt)Cd(SeCN)2]∞ is observed. Antibacterial studies of some of the complexes were carried out.
