In the title coordination polymer, {[Zn(C8H5NO4)(C3H4N2)]·0.25H2O}n, the Zn2+ cation has an N2O2 donor set involving two carboxyl­ate O atoms from two 5-amino­isophthalate anions, one N atom from a 5-amino­isophthalate anion, and one imidazole N atom displaying a slightly distorted tetra­hedral geometry with two additional O-atom neighbours, with Zn-to-ligand distances of 2.711 (2) and 2.717 (2) Å, respectively. Each 5-amino­isophthalate anion acts as a μ3-bridge linking symmetry-related ZnII ions into a layered polymeric structure parallel to (100). The asymmetric unit also comprises a disordered crystal water molecule located on an inversion centre with 0.25 occupancy. In the crystal, N—H⋯O hydrogen bonds form a three-dimensional network.

Comment top

5-Aminoisophthalic acid is often used as organic ligand to synthesise complexes with variable coordination modes. Herein, we report the crystal structure of title coordination polymer. The asymmetric unit consists of one zinc ion, one 5-aminoisophthalate anion, one imidazole and partly occupied crystal water. Each Zn ion has a N2O2 donor set and is coordinated by two carboxylate O atoms from two 5-aminoisophthalate anions, one N atom from the amino group of 5-aminoisophthalate anion, and one N atom from an imidazole, displaying a slightly distorted tetrahedral geometry (Fig. 1 and Table 1) with the two additional neighbours O1 and O3 with Zn-ligad distances of 2.711 (2) and 2.717 (2) Å, respectively. Each 5-aminoisophthalate anion acts as a µ3-bridge. So in the structure of title complex, every 5-aminoisophthalate anion links three zinc ions and every zinc ion bridges three 5-aminoisophthalate anions. This kind of connection proceeds infinitely to form a layer (Fig. 2). Whithin the crystal structure, there are N—H···O hydrogen bonds (Table 2).

Experimental top

Reaction mixture of zinc nitrate hexahydrate (29.7 mg, 0.1 mmol), 5-aminoisophthalic acid (18.1 mg, 0.1 mmol), imidazole (6.81 mg, 0.1 mmol), and potassium hydroxide (11.2 mg, 0.2 mmol) in 8 mL H2O was sealed in a 16 mL Teflon-lined stainless steel container and heated to(1) 453 K for 3 days. After cooling to the room temperature, colourless block crystals of the title complex were obtained.

Refinement top

The hydrogen atoms in all C atoms were located in geometrically idealized positions and constrained to ride on their parent atoms, with C—H = 0.93 Å and Uiso(H) = 1.2Ueq(C). The hydrogen atoms in N or O atoms can be found at reasonable positions in the difference Fourier maps and located there [Uiso(H) = 1.2Ueq(N or O)].

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.
