In title complex, [Co(C28H22N2O2)(C5H5N)2]ClO4·1.5H2O, the CoIII ion is in a slightly distorted octahedral coordination environment with the pyridine ligands in a trans arrangement. In addition to the cation and anion, the also contains three half-occupancy solvent water molecules and all components are connected via intermolecular O—H⋯O hydrogen bonds.

The free Schiff base ligand (L), it was prepared according to the method reported previously (Zhang et al., 1990). The synthesis of the title complex was carried out by mixing CoClO4.6H2O, pyridine and L with a molar ratio 1:2:1 in methanol. After the mixture was stirred for about 30 min at room temperature in air, it was filtered to remove any undissolved material. The filtrate was allowed to partially evaporate in air for several days to produce crystals suitable for X-ray diffraction with a yield about 40%.
H atoms bonded to O atoms were located in a difference Fourier map. They were refined in a riding-model approximation with O—H = 0.85 Å and Uiso(H) = 1.2Ueq(O). H atoms bonded to C atoms were placed in calculated positions with C—H distances = 0.93 and 0.98 Å, and were refined in a riding-model approximation with Uiso(H) = 1.2Ueq(C).

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. |

Cobalt complexes with tetradentate Schiff base ligands have been extensively used to mimic cobalamin (B12) coenzymes (Amirnasr et al., 2001; Cmi et al., 1998; Polson et al., 1997) and dioxygen carriers and oxygen activators (Yamada, 1999; Henson et al., 1999). Here, we report the crystal structure of a CoIII complex containing the chiral tetradentate Schiff base ligand (+)-(1R,2R)-N,N'-Bis(salicylidene)-1,2-diphenyl-1,2-ethanediamine.
The molecular structure of the title cation is shown in Fig. 1. The CoIII ion is six coordinated. The four equational sites are occupied by two N atoms and two O atoms of the tetradentate Schiff base ligand and the two axial sites are occupied by the N atoms of two pyridine ligands, forming a slightly distorted octahedral coordination environment. The Co—O and Co—NSchiff base bond lengths are consistent with the corresponding bond lengths in the CoIII Schiff base complex trans-[Co(salen)(py)2][BPh4] (Shi et al., 1995) as are the Co—Npy distances.
