Bis[bis-(1-ethyl-benzimidazol-2-ylmeth-yl) ether]cobalt(II) dipicrate dimethyl-formamide disolvate.

ABSTRACT: In the title complex, [Co(C(20)H(22)N(4)O)(2)](C(6)H(2)N(3)O(7))(2)·2C(3)H(7)NO, the Co(II) ion is coordinated by two sets of two N atoms and an O atom from two independent tridendate ligands in a distorted octa-hedral coordination environment. There are significant differences between chemically equivalent coordination bond lengths. The crystal structure is stabilized by weak inter-molecular C-H?O hydrogen bonds and weak ?-? stacking inter-actions [centroid-centroid distance 3.495?(1)?Å]. In one of the anions one nitro group is rotationally disordered about the C-N bond with refined occupancies of 0.524?(8) and 0.476?(8).

1,4-Bis(benzimidazol-2-yl)benzene dimethyl-formamide disolvate.

Project description:The aromatic mol-ecule of the title compound, C(20)H(14)N(4)·2C(3)H(7)NO, occupies a special position on an inversion center. The benzimidazole unit (planar to within 0.008?Å) forms a dihedral angle of 9.1?(2)° with the central benzene ring. The benzimidazole H atom participates in a hydrogen bond with the dimethyl-formamide solvent molecule, thus giving rise to the title 1:2 aggregate. These aggregates are further linked in the crystal structure by aromatic ?-? stacking inter-actions [centroid-centroid distance = 6.356?(2)?Å].

The metal centres are connected via the bidentate L ligands into two-dimensional polymeric layers parallel to bc plane. The dimethyl-formamide and solvent water mol-ecules participate in inter-molecular O-H?O and O-H?S hydrogen bonds, which consolidate the crystal packing.
