Chelates of Cu(II), Ni(II), Co(II), Mn(II), Fe(III), Zn(II), and dioxouranium(VI) have been prepared from p-hydroxybenzoic acid (P)-urea (U)-formaldehyde (F) copolymer (PUF). The metal-ligand ratios in the chelates were established by eiemental analysis. The probable structures were elucidated on the basis of reflectance and IR spectra in conjunction with magnetic moments. These indicated a distorted octahedral structure for all the chelates except for dioxouranium(VI) chelate. Thermogravimetric analysis has been carried out to ascertain the relative thermal stability of ligand and chelates.
