Nitrosyl Complexes. 6. Reactions of Na[Fe(CO)3NO] with Cp*M(CO)3Cl (Cp*=η5−CH3C5H4, M = Mo or W): Crystal structures of Cp*M(CO)2NO and Cp*M(μ3‐NH)(μ2‐NO)(μ2‐CO)Fe2(CO)6

Abstract

AbstractSodium nitrosylcarbonyliron reacts with methylcyclopentadienylcarbonylmetal (Mo or W) chloride in CH3OH/THF at room temperature to give Cp*Mo(CO)2NO(la) (Cp* = η5−CH3C5H4) or Cp*W(CO)2NO (1b), [Cp*Mo(CO)3]2 (2a) or [Cp*W(CO)3]2 (2b), and Cp*Mo(μ3‐NH)(μ2‐NO)‐(μ2‐CO)Fe2(CO)6 (3a) or Cp*W(μ3‐NH)(μ2‐NO)(μ2‐CO)Fe2(CO)6 (3b), respectively. Complexes 1a, 1b, 3a and 3b were analyzed by IB, NMR, MS and elemental analyses, and the crystal structures of 1b, 3a and 3b were determined by X‐ray diffraction method. The new clusters 3a and 3b have μ3‐NH ligands which were formed by reduction of NO in the synthetic reactions.
