Tetra­kis(1-phenyl-1H-imidazole-κN ³)bis­(thio­cyanato-κN)nickel(II)

Abstract

The title compound, [Ni(NCS)₂(C₉H₈N₂)₄], crystallizes with two independent half-mol­ecules in the asymmetric unit and the Ni^II ions situated on centres of symmetry. In both independent mol­ecules, the Ni^II ion displays a compressed octa­hedral environment formed by four N atoms from the 1-phenyl-1H-imidazole ligands, which define the equatorial plane, with a mean Ni—N distance of 2.119 (11) Å, and two axial N atoms from two NCS⁻ anions, with a mean Ni—N distance of 2.079 (7) Å. The crystal packing exhibits weak inter­molecular S⋯S contacts of 3.411 (2) Å.

Comment

The title compound, (I), has been obtained in a study of the conditions of the formation of thiocyanate-containing complexes with imidazole derivatives, and to investigate the influence of steric properties on the stoichiometry as well as on the stoichiometry of the resulting species.

The asymmetric unit of (I) two independent half-molecules (Fig. 1). Each Ni atom displays an octahedral coordination geometry, with six N atoms from two thiocyanate anions and four 1-phenyl-1H-imidazole ligands. The equatorial plane of the complex is formed by four Ni—N(1-phenyl-1H-imadazole) bonds with lengths from 2.105 (4) to 2.127 (3) Å, and the axial positions are occupied by two N-bonded NCS groups [Ni—N(NCS) = 2.077 (4) or 2.083 (4) Å]. These values agree well with those observed in the related [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 values of the bond angles around nickel atoms are close to those expected for a regular octahedral geometry, the N—Ni—N angles range from 87.85 (13) to 92.15 (13) °, and the thiocyanate ligands are almost linear. Weak S···S intermolecular contacts of 3.411 (9) Å contribute to the crystal packing stability.

Experimental

The title compound was prepared by the reaction of 1-phenyl-1H-imidazole (2.88 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. Analysis, calculated for C₃₈H₃₂NiN₁₀S₂: C 60.73, H 4.29, N 18.64%; found: C 60.25, H 4.33, N 18.97%. Single crystals suitable for X-ray measurements were obtained by recrystallization from methanol at room temperature.

Refinement

H atoms were positioned geometrically (C—H = 0.93–0.97 Å) and allowed to ride on their parent atoms with U_iso(H) = 1.2 times U_eq(C).

Special details

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.
