Structure and Magnetic Properties of a 2D Paddle‐wheel Dinuclear[Cu₂] Cluster‐based Polymer with 1,1‐Cyclohexanediacetate Ligand

Abstract

One new two‐dimensional (2D) CuII polymer [Cu(CHDA)(H2O)]n (1) was synthesized solvothermally based on 1,1‐cyclohexanediacetic acid (H2CHDA) ligand. Single‐crystal X‐ray diffraction analysis reveals that 1 has a 2D framework structure consisting of paddle‐wheel dinuclear [Cu2] cluster unit and CHDA2– connector, which bears a 4‐connected sql network with Schläfli symbol of (44.62). Magnetic studies indicate the presence of strong antiferromagnetic coupling (J = –302 cm–1) between the two CuII ions in the paddle‐wheel dicopper(II) entity.

Synthesis, Crystal Structure, Thermal Stability, Magnetic Property, and Biological Activity of a New Copper(II) Complex Based on 1,2,4‐Benzenetricarboxylic Acid and 2,2′‐Bipyridine

“…For years, the rational design and preparation of the transition metal complexes have attracted a great deal of interest not only for their fascinating complex structures, but also for their versatile functions . The attraction is not only confined in the field of crystal engineering and molecular topologies but also covers a broad area of research due to their numerous applications in gas absorption and separation, luminescence, catalysis, molecular magnetism, sensors and so on . Carboxyl bridged dinuclear Cu II complexes, are interesting for a theoretical point of view, since they provide the simplest magnetic interactions.…”
