Synthesis, characterization and crystal structure determination of new coordination polymers of cadmium (II) based on pyridine hydrazide ligands

Two new polymeric compounds of cadmium acetate using two isomers of pyridine hydrazide ligands have been synthesized and characterized by X-ray diffraction analysis. Structural analysis shows that both compounds were crystallized in monoclinic crystal system with P21/c space group. Coordination polymer [Cd(OAc)2(L1H)]n (1) which L1H is para pyridine hydrazide, has two dimensional sheets with rectangular net and coordination polymer [Cd2(OAc)3(L2H)L2(EtOH)]n (2) which L2H is meta pyridine hydrazide, has got herringbone structure in 2D dimension.
