Abstract

A new three-dimensional metal-organic coordination polymer, [La2(H2O)2(H2BTEC)(BTEC)], 1, was hydrothermally synthesized and characterized by single crystal X-ray diffraction. The three-dimensional framework is built up from La2O16 dimers connected by carboxylate anions. The polymer exhibits strong photoluminescence at room temperature with the main emission band at 390 nm (λex = 338 nm). Crystal data: triclinic, space group P(−1),a = 6.4486(3),b = 9.4525(5),c = 9.6238(5) Å, α= 88.24(1), β = 74.67(2), γ= 76.76(1)°,V = 550.45(5)
