A rare 3D lanthanide metal–organic framework with the rutile topology: Synthesis, structure and properties

A 3D lanthanide metal–organic framework (MOF) with the rutile topology, Yb(CTC)(DMF)·(H2O)2 (JUC-57) (CTC = cis, cis-1, 3, 5-cyclohexanetricarboxylic acid, DMF = N, N′-dimethylformamide, and JUC = Jilin University China), have been synthesized under mild conditions. It crystallizes in monoclinic symmetry with space group P21/n. The structure can be considered to be built up from six-connected inorganic and three-connected organic Secondary Building Units (SBUs) with the rutile topology, Schläfli symbol of which is (42·610·83)(4·62)2. This lanthanide MOF possesses 11.8 × 6.9 Å2 channels along the [1 0 0] direction, and 6.8 × 6.1 Å2 channels along the [0 1 1] and [0 1 −1] direction, respectively. The fluorescent and magnetic properties of JUC-57 are characterized and the result reveals that it could be potentially utilized as the multifunctional material.
