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.
