Abstract top

In the title compound, [CoCl2(C17H13N3S)2], the CoII atom exhibits a distorted octahedral coordination geometry involving two chloride ligands, one of which is split over two positions [refined site-occupancy ratio = 0.847 (18):0.153 (18)], and four N-atom donors from two 1-benzyl-2-(1,3-thiazol-4-yl)-1H-benzimidazole ligands. The two chelate rings including the CoII atom are essentially planar, the maximum deviations from the mean planes being 0.080 (2) and 0.046 (2) Å; the dihedral angle between them is 74.1 (1)°. In both ligands, the thiazole and benzimidazole rings are nearly coplanar, as indicated by the dihedral angles between their planes of 1.16 (8) and 6.29 (7)°. Each pendant benzene ring is almost perpendicular to the benzimidazole molecule to which it is attached; the dihedral angles between their planes are 75.94 (9) and 75.55 (10)°. The crystal structure is stabilized by non-classical C-H...Cl hydrogen bonding forming a three-dimensional network.

Comment top

The thiabendazole or (2-(4'-thiazolyl)benzimidazole), is an antimicrobial drug belonging to the benzimidazole derivatives which are ubiquitous in biology and biomedicine (Devereux et al. 2007), Beside its biological properties, thiabendazole is an effective ligand to coordinate transition metal ions (Kowala et al., 1971; Yan-Jua and Guang-Ganga, 2009).

The crystal structure of the title compound, show that the CoII ion adopts a distorted octahedral coordination arising from two bidentate ligands and a two Cl- anion of which one (Cl2) is splited over two positions (Cl2a and Cl2b) and four nitrogen donors from the ligands. Indeed, the refined occupancy rate of Cl2a and Cl2b sites shows that the first is occupied at 95 (2) % and the remainder in the second site respectively (Fig.1). The two heterocyclic ligands (S1N1C1C2C3) and (N2N3C4 to C10); (S2N4C18C1920) and (N5N6C21 TO C27) are nearly coplanar with dihedral angles between them of 1.16 (8) ° and 6.26 (9)° respectively. The dihedral angle between the both thiabendazole molecules surrounding the cobalt atom is of 74.1 (1)°. Each benzene ring (C12 to C17 and C29 to C34) is virtually perpendicular to the benzimidazole molecule (N2N3C5 to C10 and N5N6C21 to C27) to which it is fixed and the dihedral angle between them is 75.94 (9) for the first system and 75.55 (10) for the second.

The crystal strucrure is further stabilized by an intermolecular C—H···Cl no classic hydrogen bonds (Table 2).

Experimental top

Thiabendazole (1.22 g, 6.02 mmol) was dissolved in 20 ml of ethanol, and CoCl2.6H2O (0.48 g, 3.02 mmol) dissolved in 1 ml of water were added. After 3 days of stirring at room temperature, a single-crystal precipitated and was separated by filtration and dried at 333 K for 24 h.

Refinement top

The highest peak (2.04) and the deepest hole (-1.02) in the final Fourier map are at 0.92 Å and 0.65 Å from Cl2. The refinement of the structure in the space group P1 with a twinning model has not led to the desired result. The splitting of one chlorine position (Cl2) in the centrosymmetric group and the refinement of the occupancy rate of each position has led to a slight improvement of the refinement and there is no longer remains electronic density near the chlorine. Indeed, the refined occupancy rate of Cl2a and Cl2b sites shows that the first is occupied at 91.8 (2) % and the remainder in the second site respectively. Now, the highest peak (O.95) and the deepest hole (-0.68) in the final Fourier map are at 0.82 Å and 0.68 Å from Co1. H atoms were located in a difference map and treated as riding with N—H = 0.86 Å, C—H = 0.93 Å (aromatic), and C—H = 0.97 Å (methylene). with Uiso(H) = 1.2 Ueq (aromatic, methylene).

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 > 2σ(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.
