(Received 25 October 2012; accepted 16 November 2012; online 24 November 2012)

In the title complex, [Cu(C13H11N2O)Cl(C6H8N2)], the CuII atom adopts a distorted tetra­hedral geometry being coordinated by the phenolic O atom and the azomethine N atom of the Schiff base ligand N-salicyl­idene 2-amino­pyridine, and by the 2-amino­pyridine N atom and a Cl atom. The pyridyl N atom of the Schiff base and the imino N atom of the 4-methyl-pyridine-2-yl­imino ligand are not involved in the coordination. There is an intra­molecular N—H⋯N hydrogen bond involving the pyridine N atom and the amino group of the 2-amino­pyridine ligand. In the crystal, mol­ecules are linked via N—H⋯Cl hydrogen bonds, forming chains propagating along [001].

Comment top

The Schiff base, N-salicylidene 2-aminopyridine, has been widely studied as a potential tridentate ligand. For example, the complex Bis{2-[(2-pyridyl)iminomethyl]-phenolato}copper(II), has been prepared by (Miao et al., 2009), who reported that to a green solution of salicylaldehyde (0.19 mmol) and Cu(OAc)2.H2O (0.05 mmol) in ethanol they added slowly an enthanolic solution of 2-aminopyridine (0.22 mmol). The resulting mixture was allowed to stand and brown crystalline needles were obtained after 1 day. The same compound was prepared by an electrochemical method (Castineiras et al., 1989) and by a solution method (Parashar et al., 1988). We have used same procedure as (Miao et al., 2009), but using a 1:1:1 molar ratio that produced the yellow crystals of the title compound, whose crystal structure we report on herein.

In the title complex, Fig. 1, the copper atom has a slightly distorted tetahedral geometry. It coordinates to the phenolic atom O1 and the azomethine atom N4 of the Schiff base liagnd N-salicylidene 2-aminopyridine, and to the 2-aminopyridine atom N1 and a chlorine atom, Cl1. The Cu—O1 and Cu—N4 bond lengths are similar to those reported in related structures (Miao et al., 2009; Castineiras et al., 1989). The structure of the molecule is stablized by an intramolecular N-H..Cl hydrogen bond (Table 1).

In the crystal, the intermolecular N-H···Cl hydrogen bond (Fig. 2 and Table 1) plays an important role in linking the molecules to form chains propagating along the c axis, as shown in Fig. 3.

Experimental top

A methanolic solution of 2-(((4-methyl-pyridine-2-yl)imino)methyl)phenol (0.01 moles) and 4-methylpyridin-2-amine (0.01 moles) was added slowly to a methanolic solution of copper chloride (0.01 moles). The resulting mixture was allowed to stand and yellow plate-like crystals were obtained after ca. 7 days.

Refinement top

The NH2 H-atoms were located in a difference Fourier map and refined with distances restraints: N-H = 0.86 (2) Å. The C-bound H atoms were positioned geometrically and refined using a riding model: C—H = 0.93 and 0.96 Å, for CH and CH3 H atoms, respectively; Uiso = k × Ueq(N,C), where k = 1.5 for CH3 H atoms, and = 1.2 for other H atoms.

Geometry. Bond distances, angles etc. have been calculated using the rounded fractional coordinates. All su's are estimated from the variances of the (full) variance-covariance matrix. The cell esds are taken into account in the estimation of distances, angles and torsion angles

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.
