Synthesis and magnetic property of a dual μ-[N(CN)2] bridged copper(II) supramolecule with dinuclear unit

A dicyanamide (dca) Cu(II) supramolecular complex constructed by hydrogen-bond interactions and weak Cu–N bond interactions has been prepared and the structure was determined by X-ray diffraction analysis. The magnetic studies indicate that strong antiferromagnetic interactions exist between two Cu(II) ions of the dca-bridged dimer.
