Synthesis, Crystal Structure and Magnetic Properties of a Nickel(II) Coordination Polymer Based the V-Shaped Ligands

Abstract

A new nickel(II) coordination polymer, Ni2(DBA)2(BIDPE)2(H2O) (1) (H2DBA = 4,4′-methylenedibenzoic acid and BIDPE = 4,4′-bis(imidazole-l-yl)diphenyl ether), has been prepared by hydrothermal synthesis and structurally characterized by IR, elemental analysis, TGA and single crystal X-ray diffraction. Complex 1 features a one-dimensional chain structure based on triply bridged binuclear units, which is further interlinked into a higher-dimensional supramolecular framework by intermolecular weak interactions. Variable-temperature magnetic data shows weak antiferromagnetic behavior in 1.
