Synthesis, crystal structure and Hirshfeld surface analysis of bis­(acetyl­acetonato-κ2O,O′)(2-amino-1-methyl-1H-benzimidazole-κN3)copper(II)

Abstract

A compound of composition [Cu(C₅H₇O₂)₂(C₈H₉N₃)] was obtained. In the crystal, the Cu^II ion exhibits a square-pyramidal geometry with the ligands (two acetyl­acetone and one 2-amino-1-methyl­benzimidazole). Hirshfeld surface analysis was used to investigate the inter­molecular inter­actions.

The title compound, [Cu(C₅H₇O₂)₂(C₈H₉N₃)], crystallizes in the ortho­rhom­bic space group Pnma. In the crystal structure, the Cu^II ion is coordinated by two acetyl­acetonate ligands and one 2-amino-1-methyl-1H-benzimidazole ligand. The crystal structure features intra­molecular N—H⋯O and inter­molecular N—H⋯O hydrogen bonds, which contribute to the overall cohesion of the crystal. Hirshfeld surface analysis and two-dimensional fingerprint plots were utilized to qu­antify the inter­molecular inter­actions, revealing the relative contributions of H⋯H (61.1%), H⋯C/C⋯H (21.3%), and O⋯H/H⋯O (11.3%) contacts to the crystal packing.
