A Novel Twofold Interpenetrating 2D (3,5)-Connected Cd(II) Coordination Framework with (5 2.6)(5 5.6 4.7) Topology
Journal of Inorganic and Organometallic Polymers and Materials(2012)
Abstract
The self-assembly of 4′-(4-carboxyphenyl)-4,2′:6′4″-terpyridine (HL) with Cd(II) cation afforded one novel twofold interpenetrating 2D coordination polymer, [Cd(L) 2(H 2O) 1.5] n. In this compound, the Cd(II) atoms as 5-connected nodes are linked by the bridging ligands L acting as both linear connectors and 3-connected nodes to form a novel (3, 5)-connected 2D framework with the (5 2.6)(5 5.6 4.7) topology. Two equivalents of such 2D framework interpenetrate with each other to form a more complicated supramolecular network. Furthermore, fluorescent measurement on the powder sample shows that the complex strongly emits at 399 nm with the excitation of 331 nm. © 2011 Springer Science+Business Media, LLC.
