摘要

The reaction of [ReN(Et(2)dtc)(2)(Me2PhP)] (Me2PhP = dimethylphenylphosphine, Et(2)dtc(-) = diethyldithiocarbamate) with SbCl3 in dichloromethane results in the formation of [{ReN(Me2PhP)(Et(2)dtc)Cl}(2){ReN(Et(2)dtc)(2)}(2){SbCl3}(2)]. A {Reequivalent toN-}(4) ring with asymmetric nitrido bridges is stabilised by the co-ordination of SbCl3 onto the chloro ligands and sulphur atoms of the dithiocarbamates. The compound decomposes upon heating in acetonitrile and the fragments of the tetrameric complex re-arrange to form [ReN(Me2PhP)(E(6)dtc)Cl](4) and [ReN(Et(2)dtc)(2)]. The multinuclear rhenium compounds have been studied by X-ray crystallography. The 8-membered {Reequivalent toN-}(4) ring system in [{ReN(Me2PhP)(Et(2)dtc)Cl}(2){ReN(Et(2)dtc)(2)}(2){SbCl3}(2)] is almost planar, while that of [ReN(Me2PhP)(Et(2)dte)Cl](4) is clearly V-shaped when viewed down either diagonal Re...Re axis. A dihedral angle of 47.88(2)degrees has been found between the contributing planes. [References: 18]
