The title compound, [Cu3(C7H3NO4)4(C2H8N2)2]·C2H8N2·4H2O, was obtained by the reaction of copper(II) acetate dihydrate with pyridine-2,6-dicarboxylic acid (H2dipic) and ethylenediamine (en) in an aqueous solution. All of the CuII atoms in the trinuclear centrosymmetric title complex are six-coordinated in a distorted octahedral geometry with N2O4 and N4O2 environments for the outer and central CuII atoms, respectively. Various interactions, including numerous O—H⋯O and C—H⋯O hydrogen bonds and C—O⋯π stacking of the pyridine and carboxylate groups [O⋯centroid distances = 3.669 (2) and 3.668 (2) Å] are observed in the

To an aqueous solution of Copper(II) acetate, an aqueous solution of H2dipic and en in 1:1:1 molar ratio was added. The final volume was 30 ml. After less than 1 h stirring, the obtained blue solution was left for 3 days. Then the blue crystals of the title compound were obtained for X-ray crystallography.
The H atoms of the water molecules were found in difference Fourier maps and the O–H bond lengths were constrained to 0.85 Å. The H atoms from C–H groups were placed in calculated positions. All H atoms were refined in riding model approximation with Uiso(H) = 1.2Ueq(C) or 1.5Ueq(O).

Geometry. All s.u.'s (except the s.u. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell s.u.'s are taken into account individually in the estimation of s.u.'s in distances, angles and torsion angles; correlations between s.u.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell s.u.'s is used for estimating s.u.'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 > 2σ(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. |

Pyridine-2,6-dicarboxylic acid (also known as 2,6-dicarboxypyridine and as dipicolinic acid, H2dipic) is a water-soluble, commercially available, cheap and versatile N,O-chelator possessing diverse coordination modes, with a recognized biological function in the body metabolism (Douki et al., 2005),and in a variety of processes as an enzyme inhibitor (Murakami et al., 2003), plant preservative (Kazuhiro et al., 1994), and food sanitizer (Burdock, 1996),. The complexation of transition metal ions from dipicolinic acid has been the subject of numerousreports. The reasons for this interest are the ability of the ligand so it gave stable chelates with different coordination modes (Park et al., 2007), affinity to form strong hydrogen bonds and its biological activity in human metabolism (Xie et al., 2006). A lots of dipicolinate complexes of transition metals and main groups are known and reported (Xie et al., 2006; Aghabozorg et al., 2006). Here, we report the crystal structure of the title binuclear complex, [Cu3(C7H3NO4)4(C2H8N2)2].(C2H8N2).2H2O, in which the Pyridine-2,6-dicarboxylic acid (C7H3NO4) species acts as a momo and tridentate ligand. In the crystal structure, the copper atoms are in three types. All copper atoms exhibit an distorted octahedral coordination geometry. In the crystal structure, Cu (1) is coordinated by two dipicolinic acid ligands, and Cu (2) is coordinated by two ethylenediamine molecules and two uncoordinated O atoms of two dipicolinic acid groups linked to Cu (1). As shown in Fig.1, this causes that Cu (2) makes a bridge between two Cu (1) atoms. The bond distances of Cu(1)– O(1) and Cu(1)– O(3) is longer than Cu(1)–N(1), Cu(1)–N(2), Cu(1)–O(5) and Cu(1)–O(7) bond distances due to Jahn–Teller effect. Also 0.74 Å difference between Cu(2)–O and Cu(2)–N bonds, due to Jahn–Teller effect. There are extensive intermolecular O—H···O, N—H···O and weak C—H···O hydrogen bonds, which cause the stability of the crystal structure (Fig. 2).
