(Received 7 January 2008; accepted 10 January 2008; online 16 January 2008)

In the molecule of the title compound, [CdCl₂(C₂₄H₂₀N₂)₂], the Cd^II centre has a distorted tetrahedral coordination geometry defined by two chloride ions and two pyridine N atoms of the monodentate 2-[(triphenylmethyl)amino]pyridine ligands. Weak intramolecular N—H⋯Cl hydrogen bonds help to establish the three-dimensional architecture.

Comment top

As part of our ongoing studies on different metal complexes with 2-[N-(tri- phenylmethyl)imino] pyridine ligand, we synthesized the title compound, (I), and report herein its crystal structure. It is isomorphic with [CoCl₂(C₂₄H₂₀N₂)₂] (Fang et al., 2006) and [ZnCl₂(C₂₄H₂₀N₂)₂] (Zhang et al., 2007) and exhibits approximate C2 local point symmetry.

In the molecule of the title compound, (I), (Fig. 1) C d atom adopts a distorted tetrahedral coordination geometry with two chloride ions and two N atoms of the pyridine rings of the monodentate 2-[N-(triphenylmethyl)imino]pyridine ligands (Table 1). Because of the large volume of the 2-[N-(triphenylmethyl)imino]- pyridine ligand, the formation of a four-coordinate complex is more possible rather than six-coordinate one. Weak intramolecular N—H···Cl hydrogen bonds (Table 2) help to establish the three-dimensional architecture.

As shown in Fig. 2, the complex molecules stack in the A—B—A—B sequence along the b axis.

Experimental top

For the preparation of the title compound, (I), 2-[N-(triphenylmethyl)imino]- pyridine ligand (30 mg, 0.09 mmol) and CdCl₂ (25 mg, 0.14 mmol) were dissolved in 5 ml and 10 ml of ethanol, respectively, and then mixed. The mixed solution was stirred about 30 min and covered with hexane (10 ml). After two months, colorless crystals of (I) were obtained.

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 F^2^ against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F^2^, conventional R-factors R are based on F, with F set to zero for negative F^2^. The threshold expression of F^2^ > σ(F^2^) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F^2^ are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
