In the title compound, {[Co(C7H3NO5)(C13H14N2)(H2O)]·2H2O}n, the CoII atom is coordinated by two O atoms from a pyridine-2,6-dicarboxyl­ate N-oxide ligand, two N atoms from two 1,3-di-4-pyridylpropane ligands and one water mol­ecule, and displays a distorted square-pyramidal coordination geometry. The 1,3-di-4-pyridylpropane ligands link the CoII atoms into an infinite zigzag chain parallel to [010]. The chains are further linked through O—H...O and C—H...O hydrogen bonds, forming a three-dimensional supra­molecular network.

Comment top

In the structural investigation of metal complexes with pyridine-2,6-dicarboxylate-N-oxide (pdco), it has been found that pdco functions as a multidentate ligand with versatile coordination modes (Nathan et al., 1985; Wen et al., 2005, 2006; Wu et al., 2007). As is well known, 1,3-di-4-pyridylpropane may act in bidentate bridging or monodentate terminal modes, leading to the formation of one-, two- or three-dimensional network (Konar et al., 2003; Lai & Tiekink, 2004; Li et al., 2004). On the basis of these observations, we utilize pdco, 1,3-di-4-pyridylpropane and CoII ion as building blocks. A new one-dimensional coordination framework has been obtained from the hydrothermal treatment in an alkaline aqueous solution.

As illustrated in Fig. 1, the CoII atom exists in a distorted square-pyramidal environment, defined by two O atoms from one pdco ligand, two N atoms from two 1,3-di-4-pyridylpropane ligands and one water molecule (Table 1). The O1, O5, N2, N3i atoms (i = x, -1 + y, z) in the basal plane are alomst coplanar, and a water molecule lies at the apical position. The 1,3-di-4-pyridylpropane ligand in a bidentate bridging mode links the CoII atoms into an infinite zigzag chain, with the shortest Co···Co separation of 11.525 (3)Å and a Co—C13—Coii angle (ii = x, 1 + y, z) of 100.06 (4)°. The chains are further self-assembled into a three-dimensional supramolecular network through O—H···O and C—H···O hydrogen bonds (Table 2; Fig. 2).

Experimental top

A mixture of cobalt chloride (0.238 g, 1 mmol), pyridine-2,6-dicarboxylic acid N-oxide (0.181 g, 1 mmol), 1,3-di-4-pyridylpropane (0.198 g, 1 mmol), NaOH (0.06 g, 1.5 mmol) and H2O (12 ml) was placed in a 23 ml Teflon-lined reactor, which was heated to 433 K for 3 d 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

H atoms bound to C atoms were positioned geometrically and refined as riding atoms, with C—H = 0.93(CH) and 0.97(CH2) Å and with Uiso(H) = 1.2Ueq(C). H atoms of water molecules were located on a difference Fourier map and fixed in the refinements, with Uiso(H) = 1.5Ueq(O).
