Formation of nitride clusters by the action of NO+ on [M4H3(CO)12]–(M = Ru, Os): the synthesis and structural characterization of [Ru4(µ-H)3(CO)11(µ4-N)] and [N(PPh3)2][Os4(CO)12(µ4-N)]
Abstract
Reaction of [Ru4H3(CO)12]– with NOBF4 in CH2Cl2 give the nitride cluster [Ru4(µ-H)3(CO)11(µ4-N)] as one of the products and in the analogous reaction with [Os4H3(CO)12]– the mono-hydrido complex [Os4(µ-H)(CO)12(µ4-N)] is obtained, which upon subsequent reaction with [N(PPh3)2][NO2] gives the anion [Os4(CO)12(µ4-N)]–; the structures of [Ru4(µ-H)3(CO)11(µ4-N)] and [Os4(CO)12(µ4-N)]– have been established by X-ray analysis.
