Abstract top

The title compound, {[Zn(C8H4O5)(C10H8N2)]·H2O}n, was synthesized by reacting Zn(NO3)2, 5-hydroxyisophthalic acid and 2,2'-bipyridine under hydrothermal conditions. Self-assembly between the bridging ligands, chelating ligands and metal ions results in a one-dimensional coordination polymer, in which the ZnII atom is six-coordinate and shows a [ZnN2O4] octahedral geometry. The ribbons are interconnected by an extensive network of hydrogen bonds involving the water molecule, the hydroxyl group and the carboxylate O atoms, forming a two-dimensional layer. These layers are connected through [pi]-[pi] interactions between the pyridyl rings [centroid-to-centroid distance 3.57 (1) Å].

Comment top

The design and construction of coordination polymers has attracted much attention owing to their intriguing topologies and potential applications as functional materials (Inoue et al., 2001). Many networks with various structural motifs have been documented in the past decade (Amabilino & Stoddart, 1995). Unlike pyridine-2,4-, 3,4- 2,5- and 2,6-dicarboxylic acids, which have been widely used as bridging ligands to assemble various coordination polymers, 5-hydroxyisophthalic acid (H2hip) as a member of the multicarboxylate ligands has been rarely reported (Plater et al., 2001). We report here the synthesis and structure of a zinc(II) coordination polymer constructed from 5-hydroxyisophthalic acid and 2,2'-bipyridine (bpy).

In the title compound, the asymmetric unit contains one ZnII atom, one hip ligand, one bpy ligand and one lattice water molecule. Each ZnII atom is coordinated by four O atoms from three hip ligands (Table 1) and two N atoms from a chelating bpy ligand in a distorted octahedral geometry (Fig. 1). Each pair of adjacent ZnII atoms are bridged by two hip ligands to form a binuclear Zn subunit. The adjacent binuclear subunits are further interconnected by two hip ligands to form a one-dimensional ribbon running along the a + c direction (Fig. 2). These ribbons are decorated with bpy ligands alternately at two sides.

The ribbons are interconnected by an extensive network of hydrogen bonds involving water molecule, hydroxyl group and carboxylate O atoms (Table 2), forming a two-dimensional layer. The layers are connected through π–π interactions between the pyridyl rings with a centroid-to-centroid distance of 3.57 (1) Å.

Experimental top

A mixture of Zn(NO3)2·2H2O (0.120 g, 0.5 mmol), 5-hydroxyisophthalic acid (0.091 g, 0.5 mmol), 2,2'-bipyridine (0.078 g, 0.5 mmol), NaOH (0.04 g, 1 mmol) and water (10 ml) was sealed in a 23 ml Teflon-lined reactor, which was heated at 453 K for 6 d and then cooled to room temperature at a rate of 5 K h−1 (yield 58%). Analysis calculated for C18H14N2O6Zn: C 51.51, H 3.36, N 6.67%; found: C 51.68, H 3.64, N 6.73%.

Refinement top

H atoms were positioned geometrically and refined as riding atoms, with C—H = 0.93 Å and Uiso(H) = 1.2Ueq(C). H atoms of water molecule were located in a difference Fourier map and refined with a distance restrain of O—H = 0.85 (1) and Uiso(H) = 1.5Ueq(O).

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.
