An Investigation of the Crystal Structure of dichloro-μ-tetra(n-butyrato)dirhenium(III)

Abstract

<p>Dichloro-μ-tetra(n-butyrato)dirhenium(III) was examined by x-rays and found to consist of a centrosymmetric dimeric unit in an eclipsed rotomeric configuration with a short rhenium-rhenium bond length of 2.20(2)Å. A long rhenium-chlorine bond 2.53(1)Å is present in the molecular unit.</p> <p>The bonding in Re2(O2C.C3H7-N)4CL2 is discussed with reference to similar carboxylate dimer structures.</p> <p>A preliminary report on the structure of Re2(O4C.C3H7-N)2 is also presented.</p>
