Synthesis, Structure and Luminescent Property of a Novel Lanthanide Metal-Organic Coordination Polymer Yb3(BDC)4.5(DMF)2(H2O)3 · (DMF)2
A three-dimensional lanthanide metal-organic coordination polymer Yb3(BDC)4.5(DMF)2(H2O)3 · (DMF)2 has been synthesized by the reaction of the lanthanide metal ion (Yb3+) with 1,4-benzenedicarboxylic acid (H2BDC) under mild condition. The compound crystallizes in the triclinic system, space group PI with unit cell parameters a = 10.7428(9) Å, b = 11.2786(9) Å, c = 26.172(2) Å, α = 85.060(2)°, β = 88.1060(10)°, γ = 62.3670(10)°, V = 2798.9 (4) Å3, Z = 2. The crystal structure exhibits one-dimensional channels along the  direction. The fluorescent results showed that there were two emission peaks at 375 and 420 nm when the compound was excited by a 235 nm excitation.
