Synthesis, Crystal Structure, and Luminescent Properties of a Cadmium(II) Coordination Polymer Based on Glutaric Acid and Triazole

A new coordination polymer, [Cd7(μ3-O)2(glut)2(Hglut)2(trz)4]n (1) (H2glut = glutaric acid and Htrz = 1,2,4-triazole), has been synthesized under hydrothermal conditions, and further characterized by elemental analysis, IR, thermogravimetric analysis and single-crystal X-ray diffraction. Complex 1 features a fairly complicated three-dimensional (3D) (3,3,6,10)-connected framework constructed from two-dimensional (2D) infinite [Cd7(μ3-O)2(glut)4(Hglut)2]n layers and [Cd(trz)4]2− units. Moreover, the thermal stability and photoluminescent properties of 1 were also investigated.
