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

In a novel {[Cu(dca)(pcl)(H2O)]2}n supramolecular complex, constructed by hydrogen-bond interactions and weak Cu-N bond interactions, strong antiferromagnetic interactions exist between two Cu(II) ions of the dca-bridged dimer.
