Abstract: A three-dimensional(3D) lanthanide metal-organic coordination polymer with a three-dimensional open framework, Tm(BTC)(DMF)(DMSO), was synthesized by reaction of the lanthanide ions(Tm3+) with 1,3,5-benzenetricarboxylic acid(H3BTC) in a mixed solution of DMF(N,N'-dimethylformamide) and DMSO(dimethyl sulphoxide). This compound crystallizes in a monoclinic space group P21/n with unit cell parameters a=1.0801(2) nm, b=1.5550(3) nm, c=1.0906(2) nm, β=100.401°, V=1.8017(6) nm3 and Z=4. The compound exhibits one-dimensional channels along the [100] direction and could uptake carbon dioxide at 1×105 Pa.

Key words: Metal-organic coordination polymer, Lanthanide element, Crystal structure, Adsorption
