A novel double-helical-chain coordination polymer constructed from 2,2′-biphenyldicarboxylate-linked binuclear-copper motif

The first 1-D double-helical-chain coordination polymer, [(H2O)Cu(BPDC)] (2,2′-biphenyldicarboxylate), based upon the binuclear square pyramidal copper(II)-pair motifs has been synthesized under hydrothermal conditions and characterized by single crystal X-ray diffraction technique. [(H2O)Cu(BPDC)] crystallized in orthorhombic crystal system, space group Cmca with unit cell dimensions a=21.073(6) Å, b=7.118(2) Å and c=17.670(5) Å, Z=8.
