(Received 6 April 2008; accepted 2 May 2008; online 7 May 2008)

In the title complex, [CoCl2(C21H19N3)], the CoII atom is coordinated by one pyridine and two imine N atoms and by two chloride anions in a distorted trigonal bipyramidal geometry. The structure exhibits a pseudo-mirror plane through the metal atom, two chloride anions and the pyridine ring. In the crystal structure, the complexes are connected via inter­molecular C—H⋯Cl hydrogen bonding.

Comment top

Recently, numerous crystal structures of metal-organic complexes with Schiff base ligands derived from 2,6-diacetylpyridine have been reported (Reardon et al., 2002; Esteruelas et al., 2003; Pradhan et al., 2003; Gibson et al., 2002; Trivedi et al., 2007) in last several years. In our ongoing investigations on this topic we report here the crystal structure of the title compound.

In the crystal stucture of the title compound the CoII atom is coordinated by three N atoms from the Schiff base ligand and two Cl atoms within a distorted trigonal-bipyramid geometry (Table 1 and Fig. 1). The pyridyl N atom and the two Cl atoms are located in the equatorial plane and the apical position are occupied by the two imino N atoms.

The molecules are connected by intermolecular nonclassical C—H···Cl hydrogen bonding between the aromatic and methyl H atoms and the Cl atoms (Table 2 and Fig 2).

Experimental top

The ligand Plep (2,6-bis[(1-phenylimino)ethyl]pyridine) was prepared in high yield from condensation of two equivalents of aniline with one equivalent of 2,6-diacetylpyridine in methanol according to the literature (Mentes et al., 2001). The title compound was synthesized as follows: To a solution of Plep (1 mmol) in 10 mL methanol, a solution of CoCl2.6H2O (1 mmol) in 10 mL methanol was added dropwise at 333 K. After stirring for half an hour, the mixture was allowed to cool to room temperature and filtered off. On slow evaporation of the solvent from the filtrate at room temperature, red well shaped single crystals of the title compound were obtained in one week.

Refinement top

All H atoms were placed in geometrically idealized positions (,ethyl H atoms allowed to rotate but not to tip) and constrained to ride on their parent atoms, with C—H distances of 0.93 Å (0.96 Å for methyl H atoms) Uiso(H) = 1.2Ueq(C) (1.5 for methyl H atoms).

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. 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.
