PHOSPHORUS-CONTAINING POLYMERIC LIGAND AND ITS COMPOUNDS WITH NICKEL(II), COPPER(II), COBALT(II), IRON(III), AND LEAD(II)

The structural characteristics of a phosphorus-containing fibrous poly ligand based on polyvinyl alcohol and polyacrylonitrile and its compou nds with the transition metal ions copper(II), iron(III), cobalt(II), nickel(II), and lead(II) were studied by IR and EPR spectroscopy and b y chemical methods. The results indicated the formation of coordinatio n compounds of the above-mentioned metals with active groups of the mo dified copolymer containing two metal atoms and one twice-deprotonated phosphonic group.
