Bis(2-benzoylimino-benzimidazolinato)copper(II) (1) as the first neutral chelate of an acylimino-benzimidazoline contains guanidine and amide moieties directly coordinated to a metal atom. The ligands are arranged in trans position. The synthesis of cis-bis(pyridine)bis(N-benzoyl-O-ethyl-N′-m-nitrophenyl-isoureato) nickel(II) (2) is described. The molecular structures of both complexes were determined by X-ray crystal structure analysis.
