Ls. Bobritskaya et al., PHOSPHORUS-CONTAINING POLYMERIC LIGAND AND ITS COMPOUNDS WITH NICKEL(II), COPPER(II), COBALT(II), IRON(III), AND LEAD(II), Journal of applied chemistry of the USSR, 65(9), 1992, pp. 1610-1614
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.
