Solvothermal synthesis, crystal structure and photoluminescent property of a novel 3D cadmium(II) coordination polymer containing [Cd5(μ3-OH)2(μ3-OAc)2]6+ cores

A novel 3D coordination polymer, {[Cd5(μ3-OAc)2(μ2-OAc)2(μ3- OH)2(pam)2(4,4′-bpy)2] · CH3CH2OH}n (1) (H2pam = pamoic acid, HOAc = acetic acid, 4,4′-bpy = 4,4′-bipyridyl), was solvothermally synthesized and characterized by the single crystal X-ray diffraction. The title compound contains unprecedented [Cd5(μ3-OH)2(μ3-OAc)2]6+ pentanuclear building units which are linked through pam and 4,4′-bpy ligands to afford a three-dimensional structure. The infrared spectroscopy, thermal stability and photoluminescence of the complex were studied.
