In the title compound, [Mo(C15H22BN6)(C7H4NO)2(NO)]·C7H5NO·CH2Cl2, the central MoII atom adopts a distorted cis-MoO2N4 octahedral geometry with the hydrotris(3,5-dimethylpyrazolylborate) anion attached to the metal in an N,N′,N′′-tridentate tripodal coordination mode. Two O-bonded 4-cyanophenolate anions and a nitrosyl cation complete the coodination of the MoII atom. Two intramolecular C—H⋯O and one C—H⋯N hydrogen bonds help to establish the configuration of the complex molecule. The is stabilized by intermolecular C—H⋯N and C—H⋯O hydrogen bonds.

The title compound was synthesized from a reaction of Mo(NO)Tp*Cl2 (0.1 mmol) with p-cyanophenol (0.25 mmol) in dichloromethane in the presence of triethylammine at refluxing temperature under N2 atmosphere (Kassim et al. 2002). Dark brown plates of (I) were obtained from a slow evaporation of dichloromethane solution of the title compound at room temperature. Yield 80%.
The H atoms attached to the B atom was located in a difference map, but those attached to carbon atoms were repositioned geometrically. The H atoms were initially refined with soft restraints on the bond lengths and angles to regularize their geometry (C—H in the range of 0.93–0.98, and O—H = 0.82 Å) and Uiso(H) (in the range 1.2–1.5 times Ueq of the parent atom), after which the positions were refined with riding constraints.
Poly(pyrazolyl)borate ligands [Trofimenko (1993)] have attracted many researchers for the coordination chemistry of molybdenum complexes [Kassim et al. (2002), Jones et al. (1997) & Amoroso et al. (1994)]. In the title compound, (I), the hydrotris(3,5-dimethyl(pyrazolyl)borate ligand bonds to the central molybdenum atom in a tridentate manner through the N-atom at the 6-position of the pyrazolyl rings. Two 4-hydroxybenzonitrileate and a nitrosyl cation, bond via the O– and N-atom respectively, complete the octahedral coordination of the Mo(II) centre (Fig1). In addition, one molecule of the excess 4-hydroxybenzonitrile ligand and one molecule of CH2Cl2 solvent cystallized in the structure (Fig. 2).
The
is stabilized by three intramolecular hydrogen bonds C(5)—H(5 A)···O(2), C(10)—H(10 A)···N(7) and C(15)—H(15 A)···N(7). The crystal packing is stabilized by two C—H···O and one C—H···N intermolecular hydrogen bonds (Fig. 3).For related compounds, see: Kassim et al. (2002); Jones et al. (1997); Amoroso et al. (1994).

Experimental. The crystal was placed in the cold stream of an Oxford Cryosystems open-flow nitrogen cryostat [Cosier, J. & Glazer, A. M. (1986). J. Appl. Cryst. 19, 105–107] with a nominal stability of 0.1 K. |
Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

Poly(pyrazolyl)borate ligands [Trofimenko (1993)] have attracted many researchers for the coordination chemistry of molybdenum complexes [Kassim et al. (2002), Jones et al. (1997) & Amoroso et al. (1994)]. In the title compound, (I), the hydrotris(3,5-dimethyl(pyrazolyl)borate ligand bonds to the central molybdenum atom in a tridentate manner through the N-atom at the 6-position of the pyrazolyl rings. Two 4-hydroxybenzonitrileate and a nitrosyl cation, bond via the O– and N-atom respectively, complete the octahedral coordination of the Mo(II) centre (Fig1). In addition, one molecule of the excess 4-hydroxybenzonitrile ligand and one molecule of CH2Cl2 solvent cystallized in the structure (Fig. 2).
The crystal structure is stabilized by three intramolecular hydrogen bonds C(5)—H(5 A)···O(2), C(10)—H(10 A)···N(7) and C(15)—H(15 A)···N(7). The crystal packing is stabilized by two C—H···O and one C—H···N intermolecular hydrogen bonds (Fig. 3).
