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.
期刊介绍：
Doklady Chemistry is a journal that publishes new research in chemistry and chemical engineering of great significance. Initially the journal was a forum of the Russian Academy of Science and published only best contributions from Russia in the form of short articles. Now the journal welcomes submissions from any country in the English or Russian language. Every manuscript must be recommended by Russian or foreign members of the Russian Academy of Sciences.
