Abstract
The asymmetric unit of the title CoII complex, [Co(C13H8BrN2O)2], contains two independent molecules (A and B). In both molecules, the CoII cation is N,O-chelated by two 2-(1H-benzimidazol-2-yl)-4-bromophenolate anions in a distorted tetrahedral geometry. In molecule A, both chelating rings display an envelope conformation, with the flap Co atom lying 0.614 (6) and 0.483 (6) Å from the mean planes of the remaining atoms. In molecule B, both chelating rings are approximately planar, the maximum deviations being 0.039 (4) and 0.076 (3) Å. In the crystal, molecules are linked by classical N—H⋯O hydrogen bonds and weak C—H⋯O and C—H⋯Br hydrogen bonds into a three-dimensional supramolecular network. Extensive π–π stacking is observed between nearly parallel aromatic rings of adjacent molecules with centroid–centroid distances in the range 3.407 (3)–3.850 (4) Å.
