Abstrakt

The present work reports the synthesis, structure, and magnetic properties of a one-dimensional coordination polymer made of copper(II) chloride and 1,2,4- triazole. The coordination polymer is synthesized in hydrochloric acid at room temperature. The structure determination by single crystal X-ray diffraction reveals an array of copper atoms bridged via two chlorine and a triazole. Magnetisation data show no hysteresis at temperatures down to 2 K, but suggest antisymmetric exchange and antiferromagnetic coupling between the neighbouring spins of Cu(II) ions. This work gives impetus for the synthesis of large crystals of coordination polymers based on which magnetic properties can be studied in depth.
