The title complex, [Cu(C7H3N2O6)2(C10H8N2)(H2O)]·C4H8O, features a penta­coordinate CuII atom bound by two monodentate carboxyl­ate ligands, a bidentate 2,2′-bipyridine mol­ecule [dihedral angle between pyridine rings = 5.0 (2)°] and a water mol­ecule. The resulting N2O3 donor set defines a distorted square-pyramidal geometry with the coordinated water mol­ecule in the apical position. In the crystal, the presence of O—Hw⋯Oc (w = water and c = carbon­yl) hydrogen bonding leads to the formation of a supra­molecular chain propagating along the c axis, which associates into a double chain via C—H⋯ O and π–π contacts between pyridyl rings [centroid–centroid distance = 3.527 (3) Å]. The solvent mol­ecules, which are disordered over two orientations in a 0.678 (11):0.322 (11) ratio, occupy voids defined by the complex mol­ecules and are held in place via C—H⋯O inter­actions.

Comment top

The title complex solvate, (I), was characterized as part of on-going structural studies of copper carboxylates and their adducts (Ozair et al., 2010).

The crystallographic asymmetric unit of (I) comprises a copper(II) complex and a solvent tetrahydrofuran (thf) molecule of crystallization in a 1:1 ratio. The molecular structure of the complex in (I) is illustrated in Fig. 1 and selected geometric parameters are collected in Table 1. The Cu atom is penta-coordinate, being coordinated by two O atoms derived from two monodentate carboxylate ligand, two N atoms of the chelating 2,2'-bipyridine ligand, and an O atom derived from the coordinated water molecule. The resulting N2O3 donor set defines a square pyramidal geometry as indicated by the value of τ = 0.16 which compares to τ = 0 for an ideal square pyramid and τ = 1.0 for an ideal trigonal bipyramid (Addison et al., 1984). In this description, the coordinated water molecule occupies the apical position and each carboxylate-O atom is trans to a pyridine-N atom, Table 2. The four donor atoms defining the square plane have deviations from the least-squares plane through them of -0.089 (2), 0.090 (2), -0.097 (2), and 0.096 (2) Å for atoms O1, O7, N5, and N6, respectively; the r.m.s. deviation for the four atoms is 0.093 Å. The Cu atom lies 0.176 (2) Å out of the square plane in the direction of the O1w atom. Distortions from the ideal geometry are due to the restricted bite distance of the 2,2'-bipyridine ligand [N5–Cu–N6 = 79.95 (18) °] and to the relatively close approach of the carbonyl-O2, O8 atoms. However, the Cu···O2, O4 separations of 2.942 (4) and 3.007 (4) Å, respectively, are not considered to represent significant bonding interactions. Under these circumstances, the disparity in the C–Ocarboxylate and C–Ocarbonyl bond distances, Table 1, is not as great as might be anticipated for formal C–Ocarboxylate and C═Ocarbonyl bonds. This is due to i) the weak interaction formed by the carbonyl-O atoms with the Cu atom, and ii) the pivotal role the carbonyl-O atoms play in the supramolecular association operating in the crystal structure (see below). Each of the carbonyl-O2,O8 atoms lies to the same side of the square plane around the Cu atom and in the opposite direction to the coordinated water molecule. The dihedral angle formed between the two carboxylate aromatic rings is 82.1 (2) °, indicating that they are almost orthogonal to each other. Within the carboxylate ligands, each carboxylate group is effectively co-planar with the aromatic ring to which it is bound, with the C1–O1,O2 carboxylate having the greater twist as seen in the O1–C1–C2–C3 torsion angle of 10.0 (7) °. By contrast, one nitro group in each carboxylate ligand, i.e. containing N1 and N4, is significantly twisted out of the plane of the aromatic ring to which it is connected [the O3–N1–C4–C3 and O11–N4–C13–C12 torsion angles are -162.7 (5) and 157.4 (5) °, respectively]. The chelating 2,2'-bipyridine ligand is almost planar with the dihedral angle between the two pyridine rings being 5.0 (2) °; the small twist in the molecule is seen in the N5–C19–C20–N6 torsion angle of -2.6 (7) °.

The most prominent interactions operating in the crystal structure of (I) are O–H···O contacts occurring between the hydrogen atoms of the coordinated water molecule and the carbonyl-O atoms of a translationally related molecule; Table 2. As illustrated in Fig. 2, the water-bound hydrogen atoms effectively form a bridge between the adjacent carbonyl atoms resulting in a ten-membered {···HOH···OCOCuOCO} synthon. The result of this hydrogen bonding is the formation of a supramolecular chain along the c axis. Each supramolecular chain is connected into a double chain along c with helical topology via C–H···O contacts whereby two bipyridine-H atoms form interactions with a carbonyl-O of the second chain, and a third bipyridine-H atom forms a C–H···O contact with a nitro-O within the chain, Fig. 3 and Table 2. This arrangement brings into close proximity the 2,2'-bipyridine molecules which interdigitate, Fig. 3, allowing for the formation of π–π interactions [ring centroid(N6,C20–C24)···ring centroid(N6,C20–C24)i = 3.527 (3) Å for i: -x + 1/2, y, z - 1/2]. The double chains pack in the ac plane to form layers that stack along the b axis, Fig. 4. Within each layer, there are voids and these are occupied by the solvent thf molecules which are held in place by C–H···O interactions, Table 2 and Fig. 4. Interactions between layers are primarily of the type C–H···O as detailed in Table 2.

Experimental top

Copper(II) acetate monohydrate (Merck; 1.995 g, 0.01 mol) and 3,5-dinitrobenzoic acid (Merck, 4.24 g, 0.02 mol) were reacted in an 1:2 molar ratio hot ethanol (60 ml) for 30 minutes following a literature precedent (Fountain & Hatfield, 1965). The resulting blue powder, [Cu2(3,5-(NO2)2C6H3COO)4], was isolated in 23% yield and reacted with 2,2'-bipyridine (mole ratio = 1:1) in THF (15 ml) at room temperature. Blue-green prisms of (I) formed when the solvent was allowed to slowly evaporate off at room temperature after 2 days.

Refinement top

Carbon-bound H-atoms were placed in calculated positions (C—H 0.95 to 0.99 Å) and were included in the refinement in the riding model approximation, with Uiso(H) set to 1.2Uequiv(C). The water-bound H-atoms were located in a difference Fourier map but were were refined with a distance restraints of O–H = 0.84±0.01 Å and H···H = 1.39±0.05 Å, and with Uiso(H) = 1.5Ueq(O). The complex was found to crystallize as a 1:1 tetrahydrofuran (thf) solvate. The solvent thf molecule was found to be disordered and resolved over two distinct orientations via fractional refinement. The major component of the disorder, with a site occupancy factor = 0.678 (11), was refined with anisotropic displacement parameters but, the non-hydrogen atoms comprising the minor component were refined isotropically. Finally, the distance restraints C–O = 1.40±0.01 Å and C—C = 1.50±0.01 Å were applied to the disordered atoms. While there is an indication of pseudo C-centring (excluding the disordered atoms), there are no counterparts for atoms O3 and O11.

Special details top

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.
