Synthesis, crystal structure and Hirshfeld surface analysis of bis-(1<i>H</i>-benzimidazole-κ<i>N</i> <sup>3</sup>)bis(benzimidazole-2-carboxyl-ato-κ<sup>2</sup> <i>N</i> <sup>3</sup>,<i>O</i>)cobalt(II).

ABSTRACT: The title complex, [Co(C8H5N2O2)2(C7H6N2)2], crystallizes in the monoclinic space group P2 1 /c with one-half of the mol-ecule in the asymmetric unit. The Co2+ ion exhibits a distorted octa-hedral environment formed by two monodentate benzimidazole ligands and two bidentate benzimidazole-2-carboxyl-ate ligands. The crystal packing features N-H⋯O hydrogen bonds and C-H⋯π contacts, which generate a chain along [011]. Hirshfeld surface analysis shows that H⋯C/C⋯H (36.2%) and H⋯H (35.3%) contacts dominate the inter-molecular inter-actions, followed by O⋯H/H⋯O and N⋯H/H⋯N contributions.
