Polymer complexes of p-acrylamidyl sulphaguanidine (HL) with Ni(II), Fe(II) and Pd(II) salts have been prepared. The structures of the polymer complexes were elucidated using elemental analysis, 1H NMR, UV-Vis, IR spectroscopies, magnetic moment, molar conductance and thermal analysis. The polymer complexes were isolated in 1:1 and 1:2 (M:L) ratios. The solid monocomplexes (1:1) (M:L) were isolated in the general formula [Fe(HL)O 2SO2(OH2)2]. The biscomplexes (1:2) (M:L) solid chelates found to have the general formula [Ni(HL)2X 2]n (X = Cl-, Br-, I-, NO3, NCS- ), [Fe(HL)(en)(OSO3)(OH 2)]n and [Ni(HL)2(Py)2] nX2, while {[Pd(L)X]2}n (1:1) (X = Cl- or Br-). In all the polymer complexes the ligand and anions were found to be coordinated to the Ni(II) and Fe(II) ions. The bidentate nature of the ligand is evident from IR spectra. The magnetic and spectroscopic data indicate a octahedral geometry for complexes. The thermal behaviour of these chelates shows that the hydrated complexes loss water molecules of hydration in the first step followed immediately by decomposition of the anions and ligand molecules in the subsequent steps.
