Abstract
Crystals of the title compound are triclinic, space group P,a= 10.299(1), b= 11.566(1),c= 12.991(1)Å, α= 104.45(1), β= 105.52(1), γ= 98.54(1)°, and Z= 1. The intensities of 3250 reflections above background were collected and the structure refined by least-squares techniques to R 0.066. The molecule exists as a centrosymmetric chlorine-bridged dimer with a pseudo-octahedral environment about the rhenium atoms. The Re–Re distance [3.809(1)Å] is inconsistent with the presence of metal–metal interaction and the structure is therefore reminiscent of that of Re2Cl10.Keywords
