Description:
The 1D chain red luminescent europium coordination polymer: {[Eu 2 L 6 (DMF)(H 2 O)] · 2DMF · H 2 O} n ( I ) (L = 4-chloro-cinnamic acid anion, C 9 H 6 ClO 2 – , DMF = N, N -dimethylformamide) was synthesized by the reaction of Eu(OH) 3 and 4-chloro-cinnamic acid ligand. The structure of the coordination polymer was determined by single-crystal X-ray diffraction analysis. It reveals that there exists two crystallographically nonequivalent europium atoms in each unit of this coordination polymer and Eu 3+ ions are connected by two alternating bridging modes to form an endless polymer structure. The luminescent properties and energy transfer process in the complex are investigated at room temperature.
