The title copper coordination polymer, [Cu₃(C₈H₄O₄)₂(C₈H₅O₄)₂(C₁₀H₈N₂)₂]_n, was synthesized by reacting Cu(NO₃)₂, isophthalic acid and 1,10-phenanthroline under hydrothermal conditions. The trinuclear unit presents a central almost planar CuO₄ chromophore with the cation on a symmetry center, and two symmetry-related CuN₂O₃ groups with the metal centre in a distorted square-pyramidal environment. These units are bridged by isophthalate ligands into one-dimensional double-chain coordination polymers which are, in turn, connected by various π–π stacking interactions (face-to-face distance ca 3.45 Å) and O—H⋯O hydrogen bonds, forming a three-dimensional supramolecular network.

Comment top

The design and construction of coordination polymers has attracted much attention owing to their intriguing topologies and potential applications as functional materials (Han et al., 2008, Ma et al., 2007). Many networks with various structural motifs have been documented in the past decade (Amabilino et al., 1995). Unlike pyridine 2,4-, 3,4- 2,5- and 2,6-dicarboxylic acids which were widely reported as bridging ligands to assemble various coordination polymers, isophthalic acid (H₂ip) has been reported only scarcely in the role of multicarboxylate ligand (Han et al., 2007). We report here the synthesis and structure of the title copper(II) coordination polymer [Cu₃(C₈H₄O₄)₂(C₈H₅O₄)₂(C₁₀H₈N₂)]_n,assembled from isophthalic acid, 1,10-phenanthroline(phen) and copper(II), (I).

In I, there is one and a half Cu(II) ions (Cu1 lies on center of symmetry), one ip, one Hip and one phen ligand in each independent crystallographic unit. Each Cu2 ion is coordinated by three oxygen atoms from two ip ligands and one Hip ligand in a mono-bidentate and bidentate coordination modes and two nitrogen atoms from a chelate phen ligand to furnish a distorted square pyramidal geometry. On the other hand, each Cu1 atom is four-coordinated by four oxygen atoms, forming a slightly distorted square geometry. (Fig.1 and Table 1).

The carboxylate oxygen atoms bridge three copper atoms (Cu2, Cu1 and Cu2ⁱ) via the syn–anti O,O-bridges to form a trinuclear [Cu₃(ip)₂(Hip)₂(phen)₂] subunit (Fig. 1), which are interconnected through the bridging ip groups to form an infinite one-dimensional double chain with Cu···Cu distances of 3.755 (3) and 9.994 (3) Å (Fig. 2). The lateral phen ligands from adjacent double-chains are paired to furnish moderately strong π—π stacking interactions (face-face distance ca 3.45 (1) Å) (He et al.,2007, Han et al., 2005), which extend the double-chains into two-dimensional wavelike layers parallel to the ab plane in the lattice. These layers are further linked via strong hydrogen bonds between uncoordinated carboxylate oxygen atoms of ip ligands (Table 2), forming a three-dimensional supramolecular network.

Special details top

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.
