Diethyl acetylphosphonate complexes with 3d metal perchlorates[1]

摘要: Abstract Complexes of diethyl acetylphosphonate(deap) with 3 d metal perchlorates were synthesized and characterized by means IR electronic spectral, magnetic susceptibility conductance studies. The final solid products obtained during interaction deap salt in triethyl orthoformate are the general type [M(deap) ](ClO 4 ) n ·H 2 O (MMn 2+ , Fe Co Ni Zn ; = o 3), involving a tris-chelate complex cation, which coordinates as bidentate ligand through PO CO oxygens; these chelates contain also exclusively ionic perchlorate lattice water. In some cases preceding precipitated directly from ligand-salt reaction mixture orthoformate. other (MFe 3+ ), however, viscous oily precipitates (OH · x H ( or 3; 1–3) initially obtained. These products, functions unidentate, coordinating only oxygen, then converted to tris-chelates, treatment additional (and ether). competition between aqua ligands for inner coordination sphere ion is due fact that relatively weak ligand, giving rise field about equal strength generated group.
