Abstract
Reaction of 1-phthalazinylhydrazone of o-diphenylphosphinobenzaldehyde (HL) with Fe(II) and Co(II) perchlorates has led to complexes of different composition and structure: [Fe(HL)2](ClO4)2 · H2O (1) and [CoL2](ClO4) · H2O (2) in spite of the use of salts with the same anion. Со2+ ion undergoes oxidation to Co3+ upon complexation. The structure of the complexes has been established by NMR spectroscopy in solution and by X-ray diffraction in crystal. X-ray diffraction has shown that complexing metal ions have octahedral structure. Compound 2 forms two independent molecules in crystal.
