Abstract
The structures of iron(III) and nickel(II) complexes with the composition [FeL
2]Cl×H
2O (
1) and [Ni(HL
2')]×DMSO×0.5H
2O (
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 N
6 and N
4O
2 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.
