Crystal structure of a trinuclear dinitrogen-bridged complex: di-µ-di-nitrogen-tetrachlorobis[chlorotetrakis(dimethylphenylphosphine)rhenio]molybdenum–dichloromethane (1/1)

Abstract

The crystal structure of the title compound has been determined by Patterson methods from three-dimensional X-ray data and refined by full-matrix least squares to R 0.068 for 1 893 observed reflections. Crystals are monoclinic, space group P2₁/c, with a= 16.710(10), b= 14.164(10), c= 19.084(11)Å, β= 114.3(5)°, Z= 2. The N–N bond length is longer than those of mononuclear-dinitrogen complexes. The structure contains a linear Re–N–N–Mo–N–N–Re chain.
