Hydrothermal Synthesis and Crystal Structure of a Novel Supramolecular Coordination Polymer {[Cu (bpdc) (H2O)] 2·2H2O}

The authors present a dimeric complex prepared by hydrothermal process with the formula {[Cu (bpdc) (H2O)] 2·2H2O}, (H2bpdc = 2, 2′-bipyridyl-6, 6′-dicarboxylic acid). This molecule has been characterized by X-ray crystallography and the crystallography reveals that it crystallizes in triclinic space group P–1 with the lattice constants of a = 6.9518(14) Å, b = 8.9562(13) Å, c = 11.0139(16) Å, α = 107.082(12)°, β = 100.520(14) °, and γ = 102.167(14)°. The wide existence of water molecule forms the C(O)-H…O and O-π hydrogen bond network and extends the dimers into 3D structure. Based on the investigation of thermal analysis, water molecules are easy to release and the network is thermal stable until approximately 250°C. Supplemental materials are available for this article.
