The title complex molecule, [Ni(NCS)₂(C₁₁H₁₀N₂O)₄], has a crystallographically imposed centre of symmetry. The Ni^II atom is coordinated by the N atoms of two trans-arranged NCS⁻ anions and four 1-[4-(1H-imidazol-1-yl)phenyl]ethanone ligands in a distorted octahedral geometry. In the crystal, C—H⋯S hydrogen bonds link the complex molecules into chains parallel to the b axis. The chains are further connected by C—H⋯O hydrogen bonds, forming layers parallel to the bc plane.

Comment top

Imidazole is of considerable interest as a ligand in many biological systems in which it provides a potential binding site for metal ions. Furthermore, the isothiocyanato anion is a versatile inorganic ligand in the synthesis of coordination compounds. As a continuation of our project devoted to study the conditions of the formation of thiocyanate-containing complexes with imidazole derivatives and to investigate the influence of steric properties on the stoichiometry of the resulting species (Liu et al., 2005; Liu et al., 2006; Pang, et al., 2007; Zheng et al., 2012), we report in the paper the crystal structure of the title compound.

The molecular structure of the title compound is shown in Fig. 1. The Ni atom lies on a centre of symmetry and displays a distorted octahedral coordination geometry, with the N atoms from two trans-arranged thiocyanate anions in the axial positions [Ni—N = 2.087 (5) Å] and the N atom of four 1-[4-(1H-imidazol-1-yl)phenyl]ethanone ligands at the equatorial plane [Ni—N = 2.097 (5)-2.125 (5) Å]. These values are in agreement with those ob served for the related compounds [Ni(NCS)₂(1-methyl-1H-imidazole)₄] (Liu, et al., 2005), [Ni(NCS)₂(1-ethyl-1H-imidazole)₄] (Liu, et al., 2006), [Ni(NCS)₂(1-vinyl-1H-imidazole)₄] (Pang, et al., 2007), and [Ni(NCS)₂(1-allyl-1H-imidazole)₄] (Zheng, et al., 2012). The equatorial N—Ni—N bond angles are close to those expected for a regular octahedral geometry [86.53 (18)–93.47 (18) °]. In the crystal structure, weak intermolecular C—H···S hydrogen interactions link the molecules into chains parallel to the b axis, which are further connected by C—H···O hydrogen bonds to form two-dimensional layers parallel to the bc plane.

Experimental top

The title compound was prepared by the reaction of 1-[4-(1H-imidazol-1-yl)phenyl]ethanone (3.72 g, 20 mmol) with NiSO₄.6H₂O (1.31 g, 5 mmol) and potassium thiocyanate (0.98 g, 10 mmol) by means of hydrothermal synthesis in stainless-steel reactor with Teflon liner at 393 K for 24 h. Single crystals suitable for X-ray measurements were obtained by slow evaporation of a methanol solution at room temperature. Analysis, calculated for C₄₆H₄₀NiN₁₀O₄S₂: C 60.07, H 4.38, N 15.23%; found: C 60.21, H 4.34, N 15.36%.

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.
