(Received 5 September 2010; accepted 13 September 2010; online 25 September 2010)

In the title compound, [CoCl2(C6H8N2)2], the CoII ion is four-coordinated by two pyridine N atoms from the 2-amino-3-methyl­pyridine ligands and two chloride ions in a distorted tetra­hedral geometry. A weak intra­molecular N—H⋯Cl inter­action occurs. The crystal packing is stabilized by inter­molecular N—H⋯Cl and C—H⋯Cl hydrogen-bond inter­actions.

Comment top

2-amino-3-methylpyridine (ampy) is a common ligand and potentially can coordinate to metal centers through the N atom of amino group (Chen et al., 2005) or the pyridyl nitrogen atom (Amani Komaei et al., 1999; Ziegler et al., 2000; Castillo et al., 2001). Recently, the structure of [(ampyH)2CoX4] proton transfer compounds (X=Cl, Br) have been reported (Carnevale et al., 2010). Polar metal-halogen bonds are good hydrogen bond acceptors (Aullón et al., 1998). We report herein the synthesis and molecular structure of the title compound, [Co(ampy)2Cl2]. The compound is mononuclear with the cobalt (II) ion coordinated by two pyridyl nitrogen atoms from two ampy ligands and two chloride ions in a distorted tetrahedral geometry (Fig. 1). The Co—N and Co—Cl bond lengths and angles are within normal ranges (Table 1). The dihedral angle formed between the least squares planes of two pyridine rings is 69.5 (5)°. Crystal packing is stabilized by weak intramolecular N–H···Cl and intermolecular N—H···Cl, C—H···Cl hydrogen bond interactions (Table 2). Cl1 forms a bifurcated acceptor bond with H4A and H2B from nearby neighbors (Fig. 2).

Experimental top

A solution of 2-amino-3-methylpyridine (0.1 ml, 1 mmol) in ethanol (10 ml) was added to a solution of CoCl2.6H2O (0.12 g, 0.5 mmol) in water (10 ml) and stirred for 20 min at 50 °C. Slow evaporation of the resulting solution gave a blue precipitate which was then recrystallized from ethanol and acetonitrile (3:1 v/v). After one week, blue crystals of the title compound suitable for X-ray analysis were isolated (yield; 0.1583 g, 91.4% based on Co, decomposition > 168 °C).

Refinement top

All of the H atoms were positioned geometrically and refined as riding atoms, with C—H = 0.93Å (CH), with C—H = 0.96Å (CH3), and Uiso(H) = 1.2, 1.49Ueq(C), and with N—H = 0.86Å (NH2) and Uiso(H) = 1.2Ueq(N).

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.
