A Novel Cadmium(Ⅱ) Complex Based on Asymmetric Dicarboxylate and N-Auxiliary Ligand: Synthesis, Crystal Structure and Properties

摘要

One Cd(Ⅱ) complex based on dicarboxylate and N-auxiliary ligand, namely, [Cd(aip)(m-bix)]n(1, H2aip=5-aminoisophthalic acid, m-bix=1,3-bis(imidazol-1-yl-methyl)benzene), was successfully synthesized under hydrothermal conditions. Single-crystal X-ray diffraction analysis reveals that 1 belongs to the orthorhombic system, space group Pbca with a=14.0790(11), b=17.0038(15), c=17.3191(16), V=4146.1(6)3 ,Z=8, Dc=1.698 g·cm-3 ,μ=1.095 mm-1 , F(000)=2128, the final R=0.0268 and wR=0.0623. Complex 1 is a three-dimensional architecture with fsc-3,5-Cmce-1 topology, in which the metal ions act as rare 5-connected nodes. The TGA, XRD and luminescent properties of 1 were studied.
