| Abstract: | {ReN(Me2PhP)(Et2dtc)Cl}2{ReN(Et2dtc)2}2{SbCl3}2] — a Novel Tetranuclear Rhenium Complex with Asymmetric Nitrido Bridges The reaction of ReN(Et2dtc)2(Me22hP)] (Me2PhP = dimethylphenylphosphine, Et2dtc‐ = diethyldithiocarbamate) with SbCl3 in dichloromethane results in the formation of {ReN(Me2PhP)(Et22tc)Cl}2{ReN(Et2dtc)2}2{SbCl3}2]. A {Re≡N‐}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)(Et2dtc)Cl]4 and ReN(Et2dtc)2]. The multinuclear rhenium compounds have been studied by X‐ray crystallography. The 8‐membered {Re≡N‐}4 ring system in {ReN(Me2PhP)(Et2dtc)Cl}22ReN(Et2dtc)2}2{SbCl3}2] is almost planar, while that of ReN(Me2PhP)(Et2dtc)Cl]4 is clearly V‐shaped when viewed down either diagonal Re…Re axis. A dihedral angle of 47.88(2)° has been found between the contributing planes. |
