Synthesis, crystal structure and Hirshfeld surface analysis of (2-amino-1-methylbenzimidazole-κN3)aquabis(4-oxopent-2-en-2-olato-κ2O,O′)nickel(II) ethanol monosolvate

Abstract

The molecule of the title compound, [Ni(C5H7O2)2(C8H9N3)(H2O)]·C2H5OH, has triclinic (P\overline{1}) symmetry. This compound is of interest for its antimicrobial properties. The asymmetric unit comprises two independent complex molecules, which are linked by N—H...O and O—H...O hydrogen bonds along [111]. Hirshfeld surface analysis indicates that 71.7% of intermolecular interactions come from H...H contacts, 17.7% from C...H/H...C contacts and 7.6% from O...H/H...O contacts, with the remaining contribution coming from N...H/H...N, C...N/N...C, C...C and O...O contacts.
