In situ attained CdII-coordination polymer with (3,4,9)-connected topology based on trinuclear CdII clusters

A new CdII-coordination polymer, namely, [Cd3(nbtc)2·4H2O]n (1), has been hydrothermally synthesized with in situ generated 5-nitrobenzene-1,2,3-tricarboxylate (nbtc3−) ligand. Single-crystal X-ray diffraction study reveals that compound 1 is constructed from trinuclear CdII clusters and exhibits a previously unknown 2D (3,4,9)-connected (3.42)(32.43.5)(36.411.510.68.8) topology as well as 3D H-bonding pillared architecture. In addition, the photoluminescent property and thermal stability of 1 were also discussed.
