N3)nickel(II) bis(3-thienylacetate)In the title complex, [Ni(C3H4N2)6](C6H5O2S)2, the NiII atom displays an octahedral coordination geometry, defined by six N atoms from the imidazole ligands. Intermolecular N-H
O hydrogen-bonding interactions between the cationic complex and 3-thienylacetate anions form a three-dimensional network architecture. The two 3-thienylacetate anions are disordered, with occupancy ratios of circa 0.774 (1):0.226 (1) and ca 0.753 (5):0.247 (5).
A mixture of nickel chloride (1 mmol), 3-thienylacetic acid (1 mmol), imidazole (1 mmol), NaOH (1.5 mmol) and H2O (12 ml) was placed in a 23 ml Teflon reactor, which was heated to 433 K for three days and then cooled to room temperature at a rate of 10 K h-1. The crystals obtained were washed with water and dryed in air.
Two independent 3-thienylacetate anions are disordered and they are split into two sets of positions, with occupancy ratios of 0.774 (1):0.226 (1) and 0.753 (5):0.247 (5), respectively. Due to the significant overlap of the disordered atoms the following restraints were applied: The two rings C1 C2 C3 C4 S1 (and ring C7 C8 C9 C10 S2) and their disordered counterparts were each restrained to be flat and their equivalent bond distances were restrained to be the same within a standard deviation of 0.01 Å. All H atoms were placed at calculated positions and were treated as riding on the parent C atoms with C—H = 0.93 Å (aromatic ring), and 0.97 Å (methylene); N—H = 0.86 Å, and with Uiso(H) = 1.2 Ueq(C, 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. |

In the structural investigation of 3-thienylacetate complexes, it has been found that the 3-thienylacetate functions as a multidentate ligand [Ng et al. (2001)], with versatile binding and coordination modes. In this study, we expected to obtain a complex composed of nickel(II), 3-thienylacetate and imidazole by hydrothermal reaction. Unfortunately, the NiII atom was not coordinated by 3-thienylacetate. We finally obtained the title structure, (I), composed of cations and anions.
As shown in Fig. 1, the crystal structure of the title complex consists of [Ni(C3H4N2)6]2+ and two different 3-thienylacetate anions. The NiII atom is coordinated by six different imidazole molecules in a slightly distorted octahedral geometry. The cationic complexes link the 3-thienylacetate anions by intermolecular N—H···O hydrogen bonding interactions (table 1) to form a three-dimensional network structure (Fig. 2).
