(Received 31 July 2009; accepted 9 August 2009; online 15 August 2009)

In the title mononuclear complex, [Co(C12H17N2OS2)2], the CoII atom is four-coordinated by two N,O-bidentate Schiff base ligands, resulting in a slightly distorted trans-CoN2O2 square-planar coordination.

Comment top

There has been much research interest in Schiff base metal complexes due to their molecular architectures and biological activities (Shi et al., 2008; Xu et al., 2009). In this work, we report here the crystal structure of the title compound, (I). In (I), all bond lengths are within normal ranges (Allen et al., 1987) (Fig. 1). The Co(II) is four-coordinated in a slight distort square-planar configuration by two N atoms and two O atoms of the Schiff base ligand.

Experimental top

A mixture of 2-hydroxy-3,5-disulfanylbenzaldehyde (372 mg, 2 mmol), N,N-dimethylpropane-1,3-diamine (204 mg, 2 mmol) and CoCl2.6H2O (1 mmol, 238 mg) was stirred in methanol (10 ml) for 1 h. After keeping the filtrate in air for 7 d, red block-shaped crystals of (I) were formed.

Refinement top

All H atoms were positioned geometrically (C—H = 0.93–0.96Å, S—H = 1.20Å) and refined as riding, with Uiso(H) = 1.2Ueq(carrier) or 1.5Ueq(methyl C).

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.
