A solution of NiCl2.6H2O (24 mg, 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. Green crystals of (I) suitable for X-ray diffraction were obtained by slow evaporation after two weeks [yield: 40%].
H atoms bounded to C atoms were included in calculated positions and treated in the subsequent refinement as riding atoms, with C—H = 0.93 Å and Uiso(H) = 1.2Ueq(C). The H atoms of water was located in Fourier difference map and refined freely.

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. |

Metal-organic frameworks (MOFs) containing 1H-tetrazol and its derivatives have attracted great attentions of many research groups due to their intriguing structural diversity and potential applications in luminescence, magnetism and gas storage (Dinca, et al., 2006; Li, et al., 2007; Bronisz, 2007). However, there are rare reports of ligands based on tetrazol and carboxylate groups as building blocks for the construction of MOFs. 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 [Ni(C8H5N4O2)2(H2O)2] and two lattice water molecules (Fig. 1), atom Ni1 occupies an inversion centre and is coordinated by two N atoms from two 4-(tetrazol-1- yl)benzoate ligands and four O atoms from four water molecules in a distorted octahedral geometry. The Ni1—N1 distance of 2.0927 (15)Å is slightly lengthened, while the distances of Ni1—O1W and Ni1—O2W bonds (Table 1) is slightly shorten compared with the values observed in related complex (Zhang et al., 2007). The crystal stacking of (I) (Fig. 2) is stabilized by intermolecular O—H···O hydrogen bonds (Table 2) (Li, et al., 2006), which is similar to that in related reports (Zou, et al., 2005; Zhang, et al., 2007).
