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 direction and could uptake carbon dioxide at 1×105 Pa.
