Model reactions for nitrogen fixation. Photo-induced formation and X-ray crystal structure of [Os2(NH3)8(MeCN)2(N2)]5+ from [OsVI(NH3)4N]3+
Abstract
UV-VIS irradiation of an acetonitrile solution of [OsVI(NH3)4N](CF3SO3)3 and organic donors under degassed conditions gave [Os2(NH3)8(MeCN)2(N2)]5+; the X-ray crystal structure of the µ-dinitrogen complex has been determined and the Os–N(N2) distances found to be 1.873(9) and 1.893(9)Å.
