Mixed solvothermal synthesis and X-ray characterization of a layered copper coordination polymer, Cu(H2O)(1,3-BDC) · H2O (BDC=benzenedicarboxylate)

A novel copper coordination polymer, Cu(H2O)(1,3-BDC) · H2O was synthesized by a mixed solvothermal reaction of cupric acetate with 1,3-BDC and characterized by single-crystal X-ray diffraction. This compound crystallizes in a tetragonal space group P4/nmm with cell parameters a=19.1411(5) Å, c=6.7881(2) Å, and Z=8. Its structure contains paddle-wheel-like bi-copper clusters with the pseudo-octahedral centers of Cu(II) ion, Cu2O8(H2O)2. Every 1,3-BDC fragment links two such clusters to yield a two-dimensional open structure. It was also characterized by infrared spectroscopy, elemental analysis, inductively coupled plasma analysis, differential thermal and thermal gravimetric analyses.
