Bis[μ-2,2′-dimethyl-1,1′-(3-oxapentane-1,5-diyl)di-1H-benzimidazole-κ2N3:N3′]bis[bis(4-methoxybenzoato)-κO;κ2O,O′-cobalt(II)]

The complete molecule of the title complex, [Co2(C8H7O3)4(C20H22N4O)2], is a dimer of the paddle-wheel-type generated by crystallographic inversion symmetry. The CoII ion is pentacoordinated by three O atoms from two 4-methoxybenzoate anions (one bidentate and one monodentate) and two N atoms from two 2,2′-bis(2-methyl-1H-benzimidazole)ether ligands. This results in a very distorted trigonal–bipyramidal geometry for the metal ion, with both N atoms in equatorial sites. The dihedral angle between the benzimidazole ring systems in the ligand is 60.04 (8)°. The configuration of the molecule is supported by intramolecular C—H⋯O hydrogen bonds.

An aqueous solution (10 ml) of 4-methoxybenzoic acid (0.072 g, 0.4 mmol), 2,2'-bis(2-methylbenzimidazole)ether (0.065 g, 0.2 mmol) and Co(Ac)2 (0.049 g, 0.2 mmol) was added in and sealed in 18 ml Teflon-lined stainless steel container. The container was heated to 130 °C and held at that temperature for 72 h, then cooled to room temperature at a rate of 10 °C.h-1. And then the title compound was isolated as purple blocks.
C–bound H–atoms were geometrically positioned (C—H 0.93 Å) and refined using a riding model, with Uiso = 1.2Ueq (C).
Bis(imidazole) ligands with –CH2– spacers are a good candidate for N-donor bridging ligand (Hoskins et al., 1997). Up to now, 2,2'-bis(2-methyl-1H-benzimidazole)ether ligands, as a flexible ligand, is rarely investigated in constructing coordination polymers.
In the title compound (Fig. 1), the CoII ion is pentacoordinated by three O atoms from two 4-methoxybenzoate anions, and two N atoms from two 2,2'-bis(2-methyl-1H-benzimidazole)ether ligand. The Co—O distances are found in the range from 1.9694 (14) to 2.374 (2) Å, which is similar to previous report (Dimitrou et al., 1999). The Co—N distances are 2.0524 (18) and 2.0598 (18) Å, respectively. The
is stabilized by a weak intermolecular C—H···O hydrogen bond between the benzene H atom of 2-methyl-1H-benzimidazole ring and the O atom of diethyl ether group, with a C17—H015···O6; the methyl H atoms of 2-methyl-1H-benzimidazole ligands and the carboxylate O atoms with C8—H8c—O2 and C20—H03B—O2 (Table 1 & Fig. 2).For background to benzimidazole ligands in coordination polymers, see: Hoskins et al.

Geometry. All s.u.'s (except the s.u. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell s.u.'s are taken into account individually in the estimation of s.u.'s in distances, angles and torsion angles; correlations between s.u.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell s.u.'s is used for estimating s.u.'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. |

Bis(imidazole) ligands with –CH2– spacers are a good candidate for N-donor bridging ligand (Hoskins et al., 1997). Up to now, 2,2'-bis(2-methyl-1H-benzimidazole)ether ligands, as a flexible ligand, is rarely investigated in constructing coordination polymers.
In the title compound (Fig. 1), the CoII ion is pentacoordinated by three O atoms from two 4-methoxybenzoate anions, and two N atoms from two 2,2'-bis(2-methyl-1H-benzimidazole)ether ligand. The Co—O distances are found in the range from 1.9694 (14) to 2.374 (2) Å, which is similar to previous report (Dimitrou et al., 1999). The Co—N distances are 2.0524 (18) and 2.0598 (18) Å, respectively. The crystal structure is stabilized by a weak intermolecular C—H···O hydrogen bond between the benzene H atom of 2-methyl-1H-benzimidazole ring and the O atom of diethyl ether group, with a C17—H015···O6; the methyl H atoms of 2-methyl-1H-benzimidazole ligands and the carboxylate O atoms with C8—H8c—O2 and C20—H03B—O2 (Table 1 & Fig. 2).
