Abstract
The title compound, Re(C10H9N6O3S)(CO)(3)]center dot C3H6O, was prepared in almost quantitative yield by reaction of Re(CO)(5)Br with the thallium salt of the tris( pyrazolyl) methanesulfonate (tpms) ligand. It shows a slightly distorted octahedral geometry for the fac-Re( CO)(3)N-3 unit, with the ligand forming three six-membered N-bonded chelate rings. AC-H center dot center dot center dot O interaction between the main molecule and the solvent molecule helps to establish the crystal packing.
