Synthesis, structure and properties of a novel lanthanide metal-organic coordination polymer with three-dimensional open framework, Tm(BTC) (DMF) (DMSO)

A three-dimensional (3 D) 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 (H-3 BTC) in a mixed solution of DMF (N, N'-dimethylformamide) and DMSO(dimethyl sulphoxide). This compound crystallizes in a monoclinic space group P2(1)/n with unit cell parameters a = 1.0801 (2) nm, b = 1.5550 (3) nm, c = 1.0906 (2) nm, beta = 100.401 degrees, V = 1.8017 (6) nm(3) and Z = 4. The compound exhibits one-dimensional channels along the [100] direction and could uptake carbon dioxide at 1 x 10(5) Pa.
