In the mononuclear title compound, [Cd(C12H9O2)2(C3H4N2)2], the CdII centre has a distorted octa­hedral coordination geometry defined by four O atoms from two naphthalene­acetate ligands and two N atoms from two imidazole ligands. The mol­ecules are linked by N—H⋯O hydrogen bonds, forming a layer network.

Comment top

naphthaleneacetate is nice ligand which has versatile bonding modes to metal ions and easily forms simple complexes (Liu et al., 2006; Duan et al., 2007). Recently, we obtained the mononuclear cadmium complex, (I), its crystal structure is reported here. Recently, we obtained the title novel mononuclear complex (I), by the reaction of cadmium chloride, 1-naphthylacetic acid and imidazole in an aqueous solution, and its crystal structure is reported here.

As depicted in Fig. 1, the CdII centre in (I) presents a distorted octahedral coordination geometry, defined by four O atoms from two 1-naphthaleneacetate ligands, and two N atoms from two imidazole ligands. The structural packing is governed by N—H···o hydrogen bonding interaction (Table 1) to form a layered network (Fig. 2).

Experimental top

The title complex was prepared by the addition of a stoichiometric amount of cadmium chloride (1 mmol) and imidazole (1 mmol) to a hot aqueous solution(10 ml) of 1-naphthylacetic acid (1 mmol). the pH was then adjusted to 7.0 to 8.0 with NaOH (1 mmol). The resulting solution was filtered, and colorlee single crystals were obtained at room temperature over several days.

Refinement top

All H-atoms were placed in calculated positions with C—H = 0.93–0.97 Å, N—H = 0.86 Å; refined using a riding model with Uiso(H) = 1.2 or 1.5 Ueq(C, N).

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.
