The title polymeric compound {(C3H12N2)[Cu(C7H3NO4)2]·3H2O}n or {(pnH2)[Cu(py-2,3-dc)2]·3H2O}n (pn is propane-1,3-diamine and py-2,3-dcH2 is pyridine-2,3-dicarboxylic acid), was synthesized by reaction of copper(II) chloride dihydrate with a proton-transfer compound, propane-1,3-diammonium pyridine-2,3-dicarboxyl­ate or (pnH2)(py-2,3-dc), in aqueous solution. The anion is a six-coordinate complex (site symmetry \overline{1}), with a distorted octa­hedral geometry around CuII, consisting of two bidentate pyridine-2,3-dicarboxyl­ate groups and two O atoms of bridging ligands from (py-2,3-dc)2− fragments, which are located in trans positions. The (pnH2)2+ cation is disordered over two sites by the center of inversion. Inter­molecular hydrogen bonds, π–π [centroid–centroid distances of 3.539 (3) Å] and C—O...π stacking inter­actions [O...Cg = 3.240 (5) Å; Cg is the center of the pyridine ring], connect the various components into a supra­molecular structure.

Intermolecular intractions, such as hydrogen bonding, π-π stacking, ion pairing and donor-acceptor interactions, are famous for making aggregates of molecules. One or more of these interactions may result in the formation of specific and spontaneous self-associations or self-associated compounds. Research has shown that hydrogen bonding plays the key role in preparation of self-assembled compounds.There is a very close relationship between hydrogen bonding and formation of proton transfer compounds (Aghabozorg, Attar Gharamaleki, Ghadermazi et al., 2007; Aghabozorg, Attar Gharamaleki, Ghasemikhah et al., 2007; Aghabozorg, Daneshvar et al., 2007).

Here, we report on the synthesis and X-ray crystal structure of the title compound. Selected bond lengths, bond angles are given in Table 1. The CuIIcompound is composed of an anionic complex, [Cu(py-2,3-dc)2]2–, propane-1,3-diammonium as a counter-ion, (pnH2)2+, and three uncoordinated water molecules (Fig. 1). The CuII atom resides on a center of symmetry and is six-coordinated by two pyridine-2,3-dicarboxylate, (py-2,3-dc)2–, groups which act as a bidentate ligand through one O atom and one N atom and two O atoms of bridging (py-2,3-dc)2– ligands that occupy trans positions with [O4ii—Cu1—O4iii = 180°; ii: x - 1, y, z and iii: -x + 1, -y + 2, -z + 2] which create the title polymeric structure. On the other hand, O1—Cu1—N1—C1 and N1—Cu1—O1—C6 torsion angles are 175.1 (3)° and -176.7 (4)°, respectively indicate that two (py-2,3-dc)2– units are in the plane. In the crystal structure, the spaces between two layers of [Cu(py-2,3-dc)2]2– are filled with a layers of (pnH2)2+ cations and water molecules (Fig 2). Solvate water molecules are disordered over two sites: O1WA and O1WB with equal occupancies and O2W by the center of inversion.

A notable feature of this compound is the presence of π-π and C—O···π stacking interactions. The π-π stacking between two aromatic rings of (py-2,3-dc)2– fragments with distances of 3.539 (3) Å (1 - x, 1 - y, 2 - z) are observed (Fig. 3). The C—O···π distances are 3.240 (5) Å (C6–O2···Cg1(1 - x, 2 - y, 2 - z); Cg1 is the centroid for the N1/C1–C5 ring] (Fig. 4). Intermolecular O—H···O, O—H···N, N—H···O, C—H···O and C—H···N hydrogen bonds with D···A ranging from 2.283 (1) Å to 3.534 (13) Å (Table 2) seem to be effective in the stabilization of the crystal structure, resulting in the formation of an interesting supramolecular structure.

Experimental top

A solution of CuCl2.2H2O (85 mg, 0.5 mmol) in water (5 ml) was added to an aqueous solution of (pnH2)(py-2,3-dc) (242 mg, 1 mmol) in water (10 ml) in a 1:2 molar ratio. Blue crystals of title compound were obtained after allowing the mixture to stand for four weeks at room temperature.

Refinement top

The H(C) atom positions were calculated. H(N) and H(O) atom positions were found in difference Fourier synthesis. All hydrogen atoms were refined with use of a riding model with the Uiso(H) parameters equal to 1.2 Ueq(C) and to 1.5 Ueq(N), 1.5 Ueq(O), where U(C), Ueq(O) and U(N) are equivalent isotropic thermal parameters of the atoms to which corresponding H atoms are bonded.

The cation is disordered over two sites by a center of inversion.

Water molecules are disordered over two sites: O1WA and O1WB with equal occupancies and O2W by the center of inversion.

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.
