Synthesis, Crystal Structure and Photoluminescence of a 2D Cadmium(II) Complex, [Cd(mpac)(4, 4-bpy)(OH)]n

A 2D cadmium coordination polymer, [Cd (mpac) (4, 4-bpy) (OH)](n) (1) (Hmpac =5-methyl-2- pyrazinecarboxylic acid, 4,4-bpy=4,4-bipyridine) has been synthesized by solvothermal method and characterized by elemental analysis, IR, TGA and single-crystal X-ray diffraction. The mpac ligands link the Cd(II) atoms to form an infinite Cd-carboxylate chain. These chains are further bridged by 4,4-bpy ligands, forming a new two-dimensional layered network. Interestingly, there are small channels of 0.24x1.16 nm(2) within the 2D individual layers along the b-axis. Furthermore, the luminescent property of complex 1 was investigated at room temperature.
