Annotatsiya
The title complex, [Cu(C 7 H 5 O 3 ) 2 (C 8 H 9 N 3 ) 2 ], crystallizes in the monoclinic space group C 2/ c . The Cu II cation is located on an inversion center and adopts a distorted octahedral coordination environment defined by two aromatic N atoms from neutral 2-amino-1-methylbenzimidazole ligands and by four O atoms from two bidentate salicylate anions coordinating via their carboxylate groups. The tri-periodic supramolecular network features intra- and intermolecular O—H...O, N—H...O and C—H...O hydrogen bonds, along with π–π stacking and C—H...π interactions. 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 intermolecular interactions.
