4O,O':O'':O''')(4-benzene-1,3-dicarboxylato-5O,O':O':O'':O''')(2-1,3-di-4-pyridylpropane-2N:N')dicobalt(II)]The hydro(solvo)thermal reaction of zinc nitrate with benzene-1,3-dicarboxylic acid and 1,3-di-4-pyridylpropane in water and ethanol gave the title complex, [Co2(C8H4O4)2(C13H14N2)]n. The complex exhibits a twofold interpenetrated three-dimensional structure, which is built up from distorted square-pyramidal CoO4N and octahedral CoO5N units, and bridging benzene-1,3-dicarboxylate and 1,3-di-4-pyridylpropane ligands.
The hydro(solvo)thermal reaction was carried out at 423 K for 2 d in a 23 ml Teflon-lined acid digestion bomb followed by slowly cooling to room temperature at 6 K h−1. A single-phase product consisting of transparent purple crystals was obtained from a mixture of 1,3-di-4-pyridylpropane (0.086 g, 0.43 mmol), Co(NO3)·6H2O (0.044 g, 0.15 mmol), benzene-1,3-dicarboxylic acid (0.073 g, 0.43 mmol), H2O (5 ml) and ethanol (5 ml). Powder X-ray diffraction measurements were performed to confirm the phase purity before all chemical and physical analyses. Thermal analyses, using a Perkin–Elmer TGA7 thermal analyzer, were performed on powder samples under flowing oxygen with a heating rate of 10 K min−1. A total weight loss of 67.8% was observed from 623 to 773 K.
H atoms were positioned geometrically and refined as riding atoms, with C—H = 0.93Å (CH), 0.97Å (CH2) and Uiso(H) = 1.2Ueq(C).

The synthesis of coordination polymers, the so-called metal–organic framework, has been a subject of intense research owing to their interesting structural chemistry and potential applications in gas storage, separation, catalysis, magnetism and luminescence. A large number of these materials have been synthesized by hydro(solvo)thermal reactions with mixed organic pyridines and carboxylic acids (Kitagawa et al., 2004). They commonly adopt three-dimensional framework structures via employing metal ions as nodes and rigid or flexible organic ligands as linkers. As a further study of such complexes, we report the title compound (Fig. 1), which is isostructural with [CoZn(C8H4O4)2(C13H14N2)]n (Chen et al., 2006) and has a parallel twofold interpenetrated three-dimensional structure (Fig. 2). All the geometric parameters are within normal ranges (Table 1). The two CoII atoms are five- and six-coordinated, respectively, by one N atom of the 1,3-di-4-pyridylpropane ligand and four or five O atoms of the carboxylate ligands, giving distorted square pyramidal and octahedral geometries.
