Synthesis, crystal structure and Hirshfeld surface analysis of (2-amino-1-methyl-benzimidazole-κN (3))aqua-bis-(4-oxopent-2-en-2-olato-κ(2) O,O')nickel(II) ethanol monosolvate.

The mol-ecule of the title compound, [Ni(C(5)H(7)O(2))(2)(C(8)H(9)N(3))(H(2)O)]·C(2)H(5)OH, has triclinic (P) symmetry. This compound is of inter-est for its anti-microbial properties. The asymmetric unit comprises two independent complex mol-ecules, which are linked by N-H⋯O and O-H⋯O hydrogen bonds along [111]. Hirshfeld surface analysis indicates that 71.7% of inter-mol-ecular inter-actions 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.
