A 3D Cd(II) coordination polymer with (41263) topology: Synthesis, crystal structure and photoluminescent properties

Abstract A new coordination polymer [Cd 2 (cpta)(H 2 O) 4 ] n ( 1 ) (H 4 cpta = cis,cis,cis-1,2,3,4-cyclopentanetetracarboxylic acid) has been hydrothermally synthesized and structurally characterized by IR, elemental analysis and single-crystal X-ray diffraction. Single-crystal X-ray diffraction reveals that 1 is a six-connected pcu-type network with (4 12 6 3 ) topology. 1 also displays strong fluorescent emissions in the solid state at room temperature.
