Synthesis, Crystal Structure and Photoluminescent Property of a New Ca(Ⅱ) Compound Constructed from 5-Oxyacetateisophthalic Acid
摘要:
A new coordination polymer, namely [Ca(HOABDC)]n (1, H3OABDC=5-oxyacetateisophthalic acid), has been synthesized through hydrothermal reactions of Ca(NO3)2 and H3OABDC. The title compound crystallizes in monoclinic, space group P21/c with a=4.3043(2), b=21.4959(11), c=10.7450(6) Å, β=91.411(5)°, V=993.88(9) Å3, C10H6O7Ca, Mr=278.23, Z=4, Dc=1.859 g/cm3, F(000)=560, μ=0.659 mm-1, the final R=0.0328 and wR=0.0670 for 1469 observed reflections (I>2σ(I)). Single-crystal X-ray structural analysis reveals that compound 1 features 1D Ca(Ⅱ)-carboxylate chain-shaped subunits, which are further connected together via HOABDC2- ligands into a 3D (6,6)-connected nia-type hybrid framework. Moreover, the luminescent property and thermal stability of 1 were also investigated.
