Crystal structure of the adduct of rhenium tetrachloride oxide and rhenium chloride trioxide

Abstract

Crystals of the title compound are triclinic, space group P1, a= 5.78, b= 6.02. c= 9.08 Å, α= 114.8, β= 96.2, γ= 95.0°. The structure was refined by three-dimensional least-squares methods to R 0.059 for 654 reflections. The ReOCl₄ and ReO₃Cl units in the structure have square pyramidal and distorted tetrahedral arrangements respectively. The two molecules are linked through an oxygen atom of the ReO₃Cl unit, which thus completes a distorted octahedral co-ordination for the rhenium atom of the ReOCl₄ unit.
