Abstract
Abstract Novel chiral coordination polymers, l-1 and d-1, with the formula [Cu4(OOCCH(OH)CH2COO)2] were synthesized through a reaction of copper acetate with l-malic acid and d-malic acid, respectively, in the presence of base under solvothermal condition. The X-ray crystallography for l-1 revealed that the copper centers of the complex were alternatively linked by a bis(oxygen) bridge and mixed bridge composing of oxygen and 1,3-carboxylate to construct a one-dimensional (1D) chain structure. These 1D chains interdigitated with each other to give a 3D polymer structure as a result of the coordination interaction linking the neighboring 1-D chain. The magnetic property was studied to show strong antiferromagnetic coupling (J/k = − 596 K) within the chain and negligible one between the one-dimensional chain.
