Urothermal Synthesis of a Photoluminescent Coordination Polymer with Rutile Topology

A new coordination polymer [Cd3(btc)2(e-urea)4].(e-urea)2 (1; btc = 1,3,5-benzenetricarboxylate; e-urea = ethyleneurea) has been urothermally synthesized using ethyleneurea hemihydrate as the solvent and exhibits (3,6)-connected rutile (rtl) topology. The structure of 1 consists of trinuclear Cd units and the btc linkers. Species 1 features a non-interpenetrating three-dimensional open framework with channels filled by the e-urea additives and guest molecules. The thermogravimetric behavior and photoluminescent property of 1 were studied.
