The title compound, (C10H10NO)2[Cu(C7H3NO4)2]·CH3OH·H2O was prepared by the reaction of copper(II) nitrate hexahydrate, 8-hydroxy-2-methylquinoline, and pyridine-2,6-dicarboxylic acid in a 1:2:2 molar ratio in an aqueous solution. The geometry of the resulting CuN2O4 coordination can be described as distorted octahedral. In the crystal, there are several intermolecular O—H⋯O, N—H⋯O and C—H⋯O hydrogen bonds. An intramolecular N—H⋯O hydrogen bond occurs in one of the cations. Considerable π–π stacking interactions are also observed between the aromatic rings of the cations, with centroid–centroid distances of 3.4567 (13), 3.5342 (14), 3.6941 (14) and 3.4568 (13) Å. These non-covalent interactions connect the components, forming a three-dimensional supramolecular structure.

A solution of 8-hydroxy-2-methylquinoline (0.320 g, 2 mmol) in methanol (10 ml) and 2,6-pyridine dicarboxylic acid (0.170 g, 1 mmol) in methanol (10 ml) were mixed and stirrered until a clear solution was obtained. A solution of Cu(NO3)2.3H20 (0.121 g, 0.5 mmol) in methanol (5 ml) was added to the acid-base mixture and stirred for 30 min. Crystals of the title compound suitable for X-ray analysis were obtained by slow evaporation after two weeks.
The hydrogen atoms bonded to O and N atoms were found in difference Fourier map and refined isotropically. The water hydrogen atoms were refined with Uiso(H) = 1.2 Ueq(O) and distance restraints of O—H 0.82 (3) and 0.82 (4) Å for H12A and H12B, respectively. The C—H protons were positioned geometrically and refined as riding atoms with C—H = 0.93 Å and Uiso(H) = 1.2 Ueq(C) for aromatic C—H groups, C—H = 0.96 Å and Uiso(H) = 1.5 Ueq(C) for methyl group.

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. |

Our research focusses on water soluble proton transfer compounds as novel self-assembled systems that can function as suitable ligands in the synthesis of metal complexes. In this regard, we have reported examples of proton transfer from pyridine-2,6-dicarboxylic acid (pydcH2) to different amine base ligands (Eshtiagh-Hosseini et al. 2010a,b,c). This has resulted in the formation of some novel proton transfer compounds based on carboxylic acid ligand derivatives (Aghabozorg et al. 2008).
The molecular structure of the title compound is presented in Fig. 1. In the title compound, CuII ion is six-coordinated by two pyridine-2,6-dicarboxylate, or (pydc)2- groups and each (pydc)2- ligand is coordinating through one pyridine N atom and two carboxylate O atoms. The atoms N1 and N2 of the two (pydc)2- fragments occupy the axial positions, while atoms O1, O3, O5, and O7 form the equatorial plane [with Cu—O distances ranging from 2.1799 (16) to 2.2070 (16) Å]. The N1—Cu1—N2 angle [174.84 (5)°] deviates little from linearity. The O3—Cu1—O7 and O1—Cu1—O5 bond angles are equal to 91.22 (6)° and 94.25 (6)°, respectively. So the geometry of the resulting CuN2O4 coordination can be described as distorted octahedral. The packing diagram of the title compound is shown in Fig. 2. It is interesting to note that the space between the layers of [Cu(pydc)2]2- units is occupied by (8hmqH)+ cations and uncoordinated water and methanol molecules, which the latter bridge the anionic and cationic units via hydrogen bonds (Fig 2 and Table 1). In the crystal structure, there are several intermolecular O—H···O, N—H···O, C—H···O and intramolecular N—H···O hydrogen bonds (Fig 2 and Table 1).
There are also extensive π–π interactions (Fig. 3) between the rings of (8hmqH)+ fragments with centroid–centroid distances for Cg7—Cg10vi, Cg10—Cg11vii, Cg7—Cg7iv and Cg10—Cg7viii equal to 3.4567 (13), 3.5342 (14), 3.6941 (14) and 3.4568 (13) Å, respectively, where Cg7, Cg10 and Cg11 are the centroids of N3/C16—C19/C24, N4/C26—C29/C34 and C29—C34, respectively (symmetry codes: iv: 1 - x,2 - y,1 - z; vi: x,1 + y,z; vii:1 - x,-y,2 - z; viii: x,-1 + y,z).
In the crystal packing a wide range of non-covalent interactions, consisting of hydrogen bonding and π ···π interactions plays an important role in the stabilization of the three-dimensional supramolecular network.
