Synthesis,Structure and Luminescent Property of a New Cd(Ⅱ) Complex Containing 2-Propyl-imidazole-4,5-dicarboxylate

摘要

A new Cd(Ⅱ) complex([Cd(H2PIDC)2]n) with singly deprotonated 2-propyl-imidazole-4,5-dicarboxylate as bridging ligand was synthesized and characterized by X-ray diffraction method.Crystal data:monoclinic,space group P21/c,with a=8.2547(11),b=10.7071(15),c=13.9131(14),β=126.164(5)o,V=992.8(2)3,C16H18N4O8Cd,Mr=506.74,Z=2,Dc=1.695g/cm3,F(000)=508,μ=1.151 mm-1,R=0.0296 and wR=0.0812 for 1581 observed reflections.Singly deprotonated ligands(H2PIDC-) act as μ3-bridge and join the Cd(Ⅱ) atoms into a 2-D layer structure.The 2-D layers are further linked by intermolecular hydrogen bonds into a 3D network.The luminescent property of the complex was also investigated.
