The structures of iron(III) and nickel(II) complexes with the composition [FeL2]Cl·H2O (1) and [Ni(HL′2)]·DMSO·0.5H2O (2), where L and HL′ are monodeprotonated residues of 1′-phthalazinylhydrazones of 2-acetyl benzimidazole and 1-phenyl-3-methyl-4-formyl-5-hydroxypyrazole respectively, are determined using single crystal X-ray diffraction analysis. Both compounds crystallize in the monoclinic symmetry. The Fe(III) and Ni(II) ions in the complexes have octahedral N6 and N4O2 donor environments respectively. Due to intermolecular hydrogen bonds, the molecules of the complexes form corrugated (complex 1) and linear (complex 2) molecular chains in the crystal.
