Abstract

Hydrothermal reactions of  2-(2′,4′-dicarboxylphenoxy) benzoic acid (H3L ) with 1,4-di(pyridin-4-yl)benzene  (dpb) and 1,4-bis(2-methylimidazol-3-ium-1-yl)benzene (bimib) in the presence of Mn(OAc)2·4H2O and Zn(NO3)2·6H2O yielded three new coordination polymers, [Mn1.5(L)(dpb).H2O].H2O (1), [Zn3(L)2( bimib)]n (2) and [Zn3(L)2( bmimb)]n (3), complex 1 has a three dimensional structure formed by the combination of mono and binuclear chains , complexes 2 and 3 have identical structures with one only different in the length of the auxiliary ligands, both complexes have 3D structure. All the complexes were characterized by IR, XRD, PXRD, and thermal gravemetric analysis (TGA), furthermore the magnetic bevior of complex 1 was studied; which showed antiferromagnetic behavior.
