(Received 8 November 2007; accepted 22 November 2007; online 6 December 2007)

In the title complex, [Cd(C5H4NO)(C12H9O2)(H2O)]n, each CdII atom is coordinated by two carboxylate O atoms from one 1-naphthyl­acetate ligand, two hydroxyl O atoms from two pyridin-3-olate ligands, one N atom from another pyridin-3-olate ligand and one water mol­ecule, and displays a distorted octa­hedral coordination geometry. The compound forms infinite chains of pyridin-3-olate ligands bridging 1-naphthyl­acetate–CdII units parallel to the b axis, with a Cd⋯Cd separation of 3.578 (2) Å. The chains are further self-assembled into a supra­molecular network through inter­molecular O—H⋯O hydrogen-bonding inter­actions.

Comment top

In structural investigations of complexes containing the 1-naphthylacetic acid ligand, it has been found that this molecule can act as a multidentate ligand with a range of versatile binding and coordination modes (Chen et al., 2004; Duan et al., 2007; Liu et al., 2006; Tang et al., 2006). In this paper, we report the crystal structure of the a new Cd complex obtained by the reaction of 1-naphthylacetic acid, 3-hydroxypyridine and cadmium chloride in alkaline aqueous solution.

As illustrated in Figure 1, each CdII atom, has a distorted octahedral geometry with the six coordinating atoms being two carboxyl O atoms from one 1-naphthylacetate ligands, two hydroxyl O atoms from two pyridin-3-olate ligands, one N atom from another pyridin-3-olate ligand and one water molecule. The pyridin-3-olate ligands connect 1-naphthylacetate-CdII units to form an infinite chain parallel to the b axis with a Cd···Cd separation of 3.578 (2) Å. These chains are further assembled by intermolecular O—H···O hydrogen bonding, with the coordinating water molecules as donors and the carboxyl O atoms as acceptors, thus forming a supramolecular network (Fig. 2).

Experimental top

A mixture of cadmium chloride (1 mmol), 3-hydroxypyridine (1 mmol), 1-naphthylacetic acid (1 mmol), NaOH (1.5 mmol) and H2O (12 ml) was placed in a 23 ml Teflon reactor, which was heated to 433 K for three days and then cooled to room temperature at a rate of 10 K h-1. The crystals obtained were washed with water and dryed in air.

Refinement top

Carbon-bound H atoms were placed at calculated positions and were treated as riding on the parent C atoms with C—H = 0.93–0.97 Å, and with Uiso(H) = 1.2 Ueq(C). Water H atoms were tentatively located in difference Fourier maps and were refined with distance restraints of O–H = 0.82 Å and H···H = 1.29 Å, each within a standard deviation of 0.01 Å with Uiso(H) = 1.5 Ueq(O).

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.
