Abstract top

In the title complex, [Co(C7H5O3)(C27H27N7)]ClO4·1.5C3H7NO, the CoII ion is five-coordinated by four N atoms from a tris(N-methylbenzimidazol-2-ylmethyl)amine (Mentb) ligand and one O atom from a salicylate ligand in a distorted trigonal-bipyramidal geometry with approximate molecular C3 symmetry. The perchlorate ion is disordered over two sites with equal occupancy. One dimethylformamide solvent molecule lies on a general position and is disordered over two coplanar orientations with equal occupancy. A second dimethylformamide molecule is disordered about a twofold rotation axis. There is an intramolecular O-H...O hydrogen bond in the cation.

Comment top

The asymmetric unit of the title compound consists of a discrete [Co(Mentb)(salicylate)] cation (Fig. 1), a perchlorate anion and 1.5 molecules of DMF. The CoII ion is five-coordinate with a N4O ligand set. The Mentb ligand acts as a tetradentate N-donor, and an O atom of carboxylate groups of the salicylate completes the coordination. The coordination geometry of the CoII may be best described as distorted trigonal bipyramid (τ = 0.84), with approximat site symmetry C3. The parameter τ is defined as (β - α)/60 [where β = O1—Co—N7, α = N1—Co—N5] and its value varies from 0 (in regular square-based pyramidal) to 1 (in regular trigonal bipyramidal) [Youngme et al., 2007]. This geometry is assumed by the CoII to relieve the steric crowding. The equatorial plane is occupied by three N atoms of three benzimidazolyl groups, while the CoII ion protrudes towards O1 and is 0.528 (2) Å from the plane of atoms N1/N3/N5. The axial positions are occupyied by N7 and O1. The three benzimidazole ring arms of the Mentb ligand form a cone-shaped cavity. The distance between CoII and O2 is 3.167 (2) A, therefore O2 is not considered to be coordinated. The distances in the Mentb and salicylate are normally equal [Allen et al., 1987]. There is a weak intramolecular O-H···O hydrogen bond and the crystal structure is stabilized by weak π···π stacking interactions with ring centroid···ring centroid distances of 3.623Å(1).

Experimental top

To a stirred solution of tris(N-methylbenzimidazol-2-ylmethyl)amine (0.0899 g, 0.2 mmol) in hot MeOH (10 ml) was added Co(ClO4)2 (H2O)6 (0.0732 g, 0.2 mmol), followed by a solution of Na(salicylate) (0.0320 g, 0.2 mmol) in MeOH (5 ml). A red crystalline product formed rapidly. The precipitate was filtered off, washed with MeOH and absolute Et2O, and dried in vacuo. The dried precipitate was dissolved in DMF to a red solution that was allowed to evaporate at room temperature. The red crystals suitable for X-ray diffraction studies were obtained after three weeks. Yield, 0.091 g (53%). (found: C, 54.23; H, 4.98; N,14.01.

Refinement top

All H atoms were found in difference electron maps and were subsequently refined in a riding-model approximation with C—H distances ranging from 0.95 to 0.99 Å with Uiso(H) = 1.2 or 1.1 Ueq(C) of the carrier atom. The H atom bonded to O3 was refined isotropically.

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.
