Abstract top

In the title compound, [Mo(C44H28N4)(NO3)O]·C6H6, the porphyrin ring is centrosymmetric. The Mo atom, oxide ion and nitrate ion are equally disordered over two sites, such that the Mo atom is displaced by 0.366 (1) Å towards the oxide ion from the 24-atom mean plane of the porphyrin, and also makes a long Mo-O bond to a nitrate O atom. A centrosymmetric benzene solvent molecule is situated between adjacent porphyrin molecules.

Comment top

In this paper, we report the structure of the title compound, (I), a six-coordinate nitrate molybdenum(V)-oxo tetraphenylporphyrin with benzene as solvate, and the new approach to synthesize the compound using oxochloromolybdenum tetraphenylporphyrin as the precursor. The structure of the related compound with CH2Cl2 as solvate has been reported previously (Okubo et al. 1999).

The molecular structure of (I) is shown in Fig. 1. Both the metal complex and the benzene molecule were found to sit on a crystallographic center of symmetry. The porphyrin core of the compound has a slight wave shape. The Mo atom is displaced by 0.366 (1) Å from the 24-atom mean porphyrin plane toward the oxo ion. The nitrate ligand binds to the molybdenum atom through one of its oxygen atoms. Selected bond lengths are given in Table 1. The Mo(V)═O distance of 1.678 (9) Å in (I) is in the range of those [1.658 (2)–1.722 (6) Å] reported previously for other molybdenum(V)-oxo porphyrin complexes (Harada et al., 2004; Kim et al., 1987; Hamstra et al., 1999; Fujihara et al., 2002; Ledon & Mentzen, 1978; Liu et al., 2001; Imamura & Furusaki, 1990; Cheng & Scheidt, 1996). The O═Mo—O linkage in (I) is essentially linear with a bond angle of 174.4 (16)°. A benzene molecule is situated between two adjacent porphyrin molecules with 1:1 benzene/porphyrin stoichiometry.

Experimental top

To a toluene solution (20 ml) of (TPP)Mo(O)Cl (0.015 g, 0.020 mmol) (Ledon & Mentzen, 1978) under nitrogen was added LiAlH4 (0.0016 g, 0.42 mmol) (Aldrich Chemical Company, used as received). Then, nitric oxide (98%; Matheson Gas, purified by passing through KOH pellets and a cold trap (dry ice/acetone) to remove higher nitrogen oxides) was bubbled through the mixture for 15 min. The mixture was stirred for an additional 30 min and filtered. A dark green solid was obtained after removal of solvent under vacuum. A suitable dark green prism-shaped crystal of (I) was grown by slow evaporation of a benzene solution of the product at room temperature under nitrogen.

Refinement top

The H atoms were positioned geometrically (C—H = 0.95 Å) and refined as riding with Uiso(H) = 1.2Ueq(C). The metal, the oxo ion and the nitrate group are disordered by 50% across the center of symmetry.

Special details top

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.
