(Received 15 March 2008; accepted 29 March 2008; online 4 April 2008)

In the title compound, [Zn(C8H5N4O2)2(CH3OH)2(H2O)2]·2H2O, the ZnII ion lies on an inversion centre and is coordinated by two O atoms from two 4-(tetra­zol-1-yl)benzoate ligands, two O atoms from two methanol mol­ecules and two O atoms from two water mol­ecules in a slightly distorted octa­hedral geometry. In addition, there are two uncoordinated water mol­ecules in the crystal structure. The crystal structure is stabilized by inter­molecular O—H⋯O hydrogen bonds.

Comment top

Coordination architectures formed from 1H-tetrazol and its derivatives have attracted wide attentions in recent years, due to not only their fascinating structures and topologies, but also their potential applications in luminescence, magnetism and gas storage (Dinca, et al., 2006; Li, et al., 2007). However, there are rare reports (Zou, et al., 2005) of the coordination systems using the benzoic acids with N-heterocycle as ligands. So we synthesized several coordination compounds by such ligands. And here we report the structure of title compound (I).

The structure of (I) consists of discrete neutral unit [Zn(C8H5N4O2)2(CH3OH)2(H2O)2], and two lattice water molecules (Fig. 1), atom Zn1 lies on an inversion centre and is coordinated by two O atoms from two 4-(tetrazol-1-yl) benzoate ligands, two O atoms from two methanol molecules and two O atoms from two water molecules in a distorted octahedral geometry.The metal ion of (I) is bonded to the carboxyl group of 4-(tetrazol-1-yl) benzoate, which is remarkably different from our previous reported compound that using the same ligand with N donor coordinating to metal ion (Zhang et al., 2007). The crystal stacking of (I) (Fig. 2) is stabilized by the intermolecular O—H···O hydrogen bonds (Table 2).

Experimental top

A solution of Zn(NO3)2.6H2O (0.1 mmol) in water (5 ml) was added to a solution of 4-(tetrazol-1-yl) benzoic acid (38 mg, 0.2 mmol) and sodium hydroxide (8 mg, 0.2 mmol) in methanol (5 mL). The reaction mixture was stirred for 30 min and then filtered. Colourless crystals of (I) suitable for X-ray diffraction were obtained by slow evaporation after two weeks [yield: 46%].

Refinement top

H atoms of C were included in calculated positions and treated in the subsequent refinement as riding atoms, with C—H = 0.93 and 0.96 Å and Uiso(H) = 1.2 and 1.5 Ueq(C,N). The H atoms of water was located in Fourier difference map and refined without restraint.

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.
