Crystal structure and Hirshfeld surface analysis of bis-(2-amino-1-methyl-benzimidazole-κN 3)bis-(salicylato-κ2 O,O')copper(II).

The title complex, [Cu(C7H5O3)2(C8H9N3)2], crystallizes in the monoclinic space group C2/c. The CuII cation is located on an inversion center and adopts a distorted octa-hedral coordination environment defined by two aromatic N atoms from neutral 2-amino-1-methyl-benzimidazole ligands and by four O atoms from two bidentate salicylate anions coordinating via their carboxyl-ate groups. The tri-periodic supra-molecular network features intra- and inter-molecular O-H⋯O, N-H⋯O and C-H⋯O hydrogen bonds, along with π-π stacking and C-H⋯π inter-actions. Hirshfeld surface analysis indicates that H⋯H (43.7% contribution), C⋯H/H⋯C (35.8%), and O⋯H/H⋯O (14.1%) contacts dominate the inter-molecular inter-actions.
