Abstract/Summary

Oxorhenium(V) complexes of beta-diketonate systems have been synthesized and isolated in pure form. The red complexes n-Bu4N[ReO(R1COCHCOR2)Cl-3] (acac, R-1=R-2=CH3; bzac, R-1=CH3 and R-2=C6H5; bzbz, R-1=R-2=C6H5) have been characterized by elemental analyses, spectroscopic and other physico-chemical tools. One complex, n-Bu4N[ReO(bzbz)Cl-3] (1c) has been subjected to single-crystal X-ray analysis. In the structure of the anion, the metal has a six-coordinate octahedral environment in which the bidentate -diketone ligand is cis and trans to the terminal oxygen.
