Synthesis and Characterization of a New 2D Ca(Ⅱ) Coordination Polymer Containing 1D Calcium-oxygen Chains
摘要:
A new 2D Ca(Ⅱ) coordination polymer, [Ca(H2btc)(H2O)2]n (1, H4btc=biphenyl-3,3',5,5'-tetracarboxylic acid), has been synthesized using the hydrothermal method and characterized by single-crystal X-ray diffraction, elemental analysis, IR, thermogravimetric analysis, and photoluminescent analysis. Complex 1 crystallizes in the monoclinic system, space group C2/c with a=17.5676(15), b=11.4496(8), c=7.6197(8) Å, β=102.787(2)°, V=1494.6(2) Å3, Z=4, Dc=1.797 Mg·m-3, μ=0.483 mm-1, F(000)=832, the final R=0.0348 and wR=0.0915 for 1521 observed reflections with I>2σ(I). Complex 1 has a 2D network containing 1D calcium-oxygen chains. These 2D networks are further connected by O-H…O hydrogen bonding interactions to generate a 3D supramolecular structure.
