In the title complex, [Co(C22H18N2O4)(CN)(H2O)]·0.5CH3CN, the CoIII cation is N,N′,O,O′-chelated by a 6,6′-dimethoxy-2,2′-[1,2-phenylenebis(nitrilomethanylylidene)]diphenolate dianion, and is further coordinated by a cyanide anion and a water molecule in the axial sites, completing a distorted octahedral coordination geometry. In the crystal, pairs of bifurcated O—H⋯(O,O) hydrogen bonds link adjacent molecules, forming centrosymmetric dimers. The acetonitrile solvent molecule shows 0.5 occupancy.

A solution of CoL (0.008 g, 0.01 mmol) (L = N,N'-bis(2-oxy-3-methoxybenzylidene)-1,2-diaminobenzene) (Costes et al., 2000) in 30 ml of CH3CN was added dropwise to a solution of LiTCNQ (0.006 g, 0.03 mmol) [TCNQ = 2,2'-(2,5-cyclohexadiene-1,4-diylidene)bis-propanedinitrile] in 20 mL of H2O solution. The reaction was carried out under oxygen-free nitrogen, using standard Schlenk techniques and degassed solvents. Red-brown single crystals suitable for X-ray determination were obtained in seven days. Elemental Anal. Calc. for C48H43N7O10Co2: C, 58.72; H, 4.41; N, 8.56 wt%, Found: C, 58.66; H, 4.50; N, 8.59 wt%.
H atoms were placed in calculated positions with C—H = 0.93–0.96 Å and O—H = 0.85 Å, and refined in riding mode with Uiso(H) = 1.5Ueq(C,O) for methyl and water H atoms, and 1.2Ueq(C) for aromatic H atoms. The disordered acetonitrile solvatete molecule is treated with 50% occupancy, and the bonds of which is restricted by a series of commonds: dfix 1.15 0.001 n4 c24, dfix 1.47 0.001 c24 c25, and dfix 2.62 0.001 n4 c25 to keep the linear configuration.

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes. |
Refinement. dfix 1.15 0.001 n4 c24 dfix 1.47 0.001 c24 c25 dfix 2.62 0.001 n4 c25 isor 0.01 c24 n4 dfix 1.50 0.01 c24 c25 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 > 2sigma(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. |

Transition metal complexes with spectroscopic and magnetic properties are currently of considerable interest. In continuation of the studies of salen type transition metal complexes, we present here the synthesis and the crystal structure of the title compound. The similar structure has been reported by us, both of which are unexpected products (Lin et al., 2011).
The bond-valence calculation (Spek, 2009) indicate that the cobalt is in +3 states, which should be produced by LiTCNQ oxidating Co(II) atom [TCNQ = 2,2'-(2,5-cyclohexadiene-1,4-diylidene)bis-propanedinitrile], meanwhile, the TCNQ decompose to produce cyandio group. The Co(III) ion is six-coordinated by two imino nitrogen atoms and one nitrogen atom from the decomposition of LiTCNQ and two phenolate oxygen atoms from the ligand and one oxygen from the hydrate group (Fig. 1). The Co—N bond distances range from 1.886 (3) Å to 1.890 (2) Å and the Co—O bond distances range from 1.884 (2) Å to 2.031 (2) Å, in accordance with the reported values. The axially coordinated hydrate oxygen atoms form H-bonding with four oxygen atoms of the adjacent ligand constructing dimer (Table 1). One acetonitrile molecule is co-crystallized with the dimer.
