Crystal structure and Hirshfeld surface analysis of bis(2-amino-1-methylbenzimidazole-κ<i>N</i> <sup>3</sup>)bis(salicylato-κ<sup>2</sup> <i>O</i>,<i>O</i>′)copper(II)
The title complex, [Cu(C<sub>7</sub>H<sub>5</sub>O<sub>3</sub>)<sub>2</sub>(C<sub>8</sub>H<sub>9</sub>N<sub>3</sub>)<sub>2</sub>], crystallizes in the monoclinic space group <i>C</i>2/<i>c</i>. The Cu<sup>II</sup> 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 <i>via</i> 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.
