The octahedral nitrosyl complexes [MoCl(NO)(3-PhCH=CHCOpy)(TpMe,Me)] and [MoCl(NO){3,5-(MeCO)2py}(TpMe,Me)] (py = pyridyl) were synthesized and characterized spectroscopically. Both complexes underwent reduction and oxidation giving anionic and cationic species, respectively. Both complexes were also characterized by X-ray crystallography that confirmed their essential octahedral geometry and showed that the Mo-NO bond distance reflected the acceptor ability of the pyridine ligands.
