- Аннотация: 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.Hetarylhydrazones resulting from the condensation of heterocyclic hydrazines and carbonyl compounds are wide-spread polyfunctional systems in contemporary bioinorganic, medicinal, coordination, and analytical chemistry [1]. These compounds show various biological activity [2], high complexing ability [3], sensor [4] and electrochemical properties [5], etc.Hydralazine, hydrazinophthalazine hydrochloride, is well known as hypotensive medicinal that decreases arterial tension [6]. 1-Hydrazinophthalazine hydrazones also show distinct biological activity [7] and can form mono- and polynuclear metal complexes [8–10]. In this work, we used o-diphenylphosphinobenzaldehyde as a carbonyl component whose derivatives produce with N-nucleophiles stable complexes employed in catalysis [11]. Iron(II) and cobalt(II) complexes display interesting magnetic and spin-crossover properties [12, 13]. Therefore, the aim of this work is to study complexing ability of o-diphenylphosphinobenzaldehyde and 1-hydrazinophthalazine condensation product (HL) toward iron(II) and cobalt(II) ions.
