New One-dimensional Chain Compounds of [M (pdz) Cl 2 ] n (M=Cu(II), Fe(II), Mn(II); pdz = pyridazine and Their Magnetic Properties

Abstract

Three novel one-dimensional coordination polymers with pyridazine (pdz),[M (pdz) Cl 2 ] n (M = Cu (II) ( 1 ), Fe (II) ( 2 ), Mn (II) ( 3 )), were synthesized and characterized. All the compounds have one-dimensional zigzag chain structures. The copper ion in compound 1 has a planer coordination sphere with two bridging pdz ligands and two C1 − anions, while the metal ions in the other compounds have a distorted octahedral environment with pdz and Cl − groups both acting as bridges. The magnetic data of these compounds show antiferromagnetic interaction between the magnetic centers within the chains.
