The complex Re2Cl6(P-n-Bu3)2 prepared in situ reacts with CH3CN to form a blue-green solution. Addition of the chelating phosphine bis(diphenylphosphino)methane (dppm) results in the formation of the complex [Re2Cl3(μ-dppm)2(NCCH3) 2][Cl] (1) upon heating. The two acetonitrile molecules adopt a trans geometry on the rhenium center with the axially coordinated chlorine. The analogous trans benzonitrile species [Re2Cl3(μ-dppm)2(NCC6H 5)2][Cl] · 2CH2Cl2 (2) is synthesized under the same reaction conditions. The coupling constants of the AA′BB′ 31P{1H} NMR spectra of the compounds were elucidated from 31P-31P homonuclear J-resolved NMR experiments. Additional characterization methods include 31P{1H} NMR spectroscopy, UV-vis spectroscopy, and X-ray crystallography.
