In the hydrothermally prepared title coordination polymer, [Ni(C2H6NO3S)2(C12H10N4)]n, the NiII ion and the 1,4-bis(1H-imidazol-1-yl)benzene ligand occupy special positions on inversion centers. The metal ion shows a slightly distorted octahedral coordination geometry, being linked to two N atoms of two 1,4-bis(imidazol-1-yl)benzene ligands and to two O and two N atoms of two chelating 2-aminoethanesulfonate ligands. The 1,4-bis(imidazol-1-yl)benzene ligands bridge symmetry-related NiII ions forming polymeric chains along the [110] direction.

Reagents and solvents used were of commercially available quality. A water solution (10 ml) of 2-aminoethanesulfonic acid (2.0 mmol) and KOH(2.0 mmol) was mixed with water solution (10 ml) of Ni(NO3)2.2H2O (1.0 mmol). 1,4-Bis(imidazol-1-yl)benzene (1 mmol) was added to the mixture, then dropped into a 23 ml Teflon-stainless steel reactor and heated at 423 K for 4 d. After cooling to room temperature, single crystals of the title compound were obtained (yield 30%). Analysis found (%): C37.27, H 4.36, N 16.32; calculated (%): C 37.14, H 4.19, N 16.24, IR (KBr, cm-1): 1031, 1166, 1233 (–SO3), 3256.6, 3300.8 (N—H).
All H atoms were placed in idealized positions (C—H = 0.93–0.97 Å, N—H = 0.90 Å) and refined as riding atoms with Uiso(H) = 1.2Ueq(C or N).

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. |

Taurine, an amino acid containing sulfur, has important physiological functions. In fact, taurine is one of the most abundant free amino-acid-like compounds found in the heart, the skeletal muscles and the nervous system. As part of our research on taurine complexes we report here the synthesis and crystal structure of the title nikel(II) complex with taurine and 1,4-bis(imidazol-1-yl)benzene.
The crystal structure shows that two taurine anions chelate to the NiII ion via terminal N and O atoms. In addition the NiII ion is coordinated to two bridging 1,4-bis(imidazol-1-yl)benzene ligands to form one-dimensional polymer. The NiII ion and 1,4-bis(imidazol-1-yl)benzene ligand are located on inversion center. The coordination environment around nickel(II) is shown in Fig. 1. The NiII atom is six-coordinated in a distorted octahedral geometry. N-H···O and C-H···O hydrogen bonds assemble the coordination polymers into a three-dimensional supramolecular network (Fig. 2). One of the taurine N–H groups is not involved in hydrogen bonding.
