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.

Graphical abstractA novel photoluminescent cadmium 3D coordination polymer with 1D open channels has been successfully prepared under solvothermal conditions, which is the first example of coordination polymer composed of [Cd5(μ3-OH)2(μ3-OAc)2]6+ clusters with mixed organic linkers.Figure optionsDownload full-size imageDownload as PowerPoint slide
