Chelate polymers of Mn (II), Co (II), Ni (II), Cu (II) and Zn (II) have been prepared with the ligand derived from adipyl bis-2-aminobenzothiazole having equimolar stochiometry of the cations and the ligands. In the present communication, a detailed study of X-Ray diffraction have been undertaken. The synthesized chelate polymers are coloured, amorphous, solid and highly insoluble in aqueous and common organic solvents. On the basis of X-Ray diffraction data, an orthorhombic crystal system has been proposed for the chelate polymers. The diffraction data were also used to index the compounds and for determination of various parameters.
