Abstract: A three-dimensional lanthanide metal-organic coordination polymer Yb-3(BDC)(4.5)(DMF)(2)(H2O)(3) center dot (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) angstrom, b = 11.2786(9) angstrom, c = 26.172(2) angstrom, alpha = 85.060(2)degrees, beta = 88.1060(10)degrees, gamma = 62.3670(10)degrees, V = 2798.9 (4) angstrom(3), Z = 2. The crystal structure exhibits one-dimensional channels along the [011] 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.
