(Received 12 January 2013; accepted 18 January 2013; online 2 February 2013)

In the title complex, [Cd(C13H8N5)2(C2H5OH)2], the CdII cation is located on an inversion center and coordinated by two deprotonated 2-(1H-benzotriazol-1-yl)-1H-benzimid­azol-1-ide (L) ligands and two ethanol mol­ecules in a distorted N4O2 octa­hedral geometry. In the L ligand, the dihedral angle between benzoimidazole and benzotriazole ring systems is 10.8 (3)°. In the crystal, the complex mol­ecules are connected by O—H⋯N hydrogen bonds; inter­molecular π–π stacking is also observed [centroid–centroid distances of 3.668 (5) Å between triazole and benzene rings and 3.780 (5) Å between imidazole rings].

Comment top

Over the past decades, we lay much stress on the complexation of metal ions by nitrogen heterocyclic compounds as their applications in the areas of optical, lectronic properties and magnetice (Zhou et al., 2006; Batten & Robson, 1998; Zaworotko, 1994).

The title compound possesses the benzotriazole and the benzimidazole rings and can offer possibilities to form complicated coordination complexes (Wu et al. 2009). In the crystal, the asymmetric unit contains one half Cd2+ cation, one organic L ligands and one ethanol molecules. The Cd2+ is coordinated by four N atoms from two different L ligands and two O atoms from two ethanol molecules. Molecules are connected by O—H···N hydrogen bonds and π-π interactions [centroid–centroid distance = 3.668 (5) and 3.780 (5) Å] involving related triazole, imidazole and benzene rings.

Experimental top

To a yellow solution of L (35 mg, 0.15 mmol) and Cd(NO3)2 (52.3 mg, 0.3 mmol) in ethanol (15 ml) were placed in a Teflon lined stainless steel autoclave and heated at 120 °C for 3 days under autogenous pressure. Then it was allowed to cool to room temperature. Stick-shaped crystals were collected in 50% yield. The crystals were repeatedly washed with ethanol and air-dried.

Refinement top

Ethanol H atom was located in a difference Fourier map and positional parameters were refined, Uiso(H) = 1.5Ueq(O). The C-bound H atoms were included in calculated position and refined in riding-model approximation with C—H = 0.93 Å, Uiso(H)= 1.2Ueq(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.
