Bis(3-methylphenolato-κO)(nitrosyl-κN)[tris(3,5-dimethylpyrazol-1-yl-κN2)hydridoborato]molybdenum(II)

The title complex, [Mo(C15H22BN6)(C7H7O)2(NO)], contains an {MoNO}4 core stabilized by κ3-hydrotris(3,5-dimethylpyrazol-1-yl)borate, [TpMe2]−, and two anionic m-cresolate ligands, leading to a distorted octahedral geometry for the Mo atom. The short Mo—O bond...

Description
Summary:The title complex, [Mo(C15H22BN6)(C7H7O)2(NO)], contains an {MoNO}4 core stabilized by κ3-hydrotris(3,5-dimethylpyrazol-1-yl)borate, [TpMe2]−, and two anionic m-cresolate ligands, leading to a distorted octahedral geometry for the Mo atom. The short Mo—O bond lengths [1.935 (2) and 1.971 (2) Å], as well as large Mo—O—Csp2 angles [134.2 (2) and 143.54 (19)°], indicate dπMo—pπO interactions, which are clearly weaker when compared with {Mo(NO)(TpMe2)} alkoxides. The nitrosyl system is virtually linear [179.3 (3)°] with Mo—N and N—O bond lengths of 1.760 (2) and 1.205 (3) Å, respectively. Intra- and intermolecular C—H(Ph or CH3)...π(Ph) interactions between adjacent phenyl rings are found in the crystal structure (dH...Ph in the range 2.743–2.886 Å). One of the Ph rings shows disorder, i.e. swinging in the ring plane.
