Abstract :
Two novel five-coordinate cis-dioxorhenium(V) complexes of the general formula ReO2[R2NCH2CH2S][PPh3] (R2N=Et2N, complex 1 and R2N=(o-CH3OC6H4N(CH2CH2)2N, complex 2) have been synthesized by reacting ReOCl3(PPh3)2 with the respective bidentate ligands R2NCH2CH2SH. The complexes have been characterized by elemental analysis, IR, NMR spectroscopies and X-ray crystallography. X-ray crystallographic studies showed that the coordination geometry around rhenium is distorted trigonal bipyramidal. The basal plane is defined by the two doubly bonded oxygen atoms and the sulfur of the bidentate ligand, while the nitrogen of the ligand and the phosphorus occupy the apical positions.
