A series of three-dimensional lanthanide coordination compounds with rutile topology, M(CTC)(DMF)(H2O)center dot (DMF)(H2O) (M = Tb (1), Dy (2), Ho (3), Er (4), and Tm (5), CTC = cis,cis-1,3,5-cyclohexanetricarboxylic acid, DMF = N,N'-dimethylformamide), have been synthesized under mild conditions. They are isomorphous and crystallize in monoclinic symmetry with space group P2(1)/n. The structure can be considered to be built up from metallic 6-connected and organic 3-connected building units with vertex symbol (4.4.4.4.6(4).6(4)). These lanthanide coordination compounds possess 10.4 x 10.1 angstrom(2) channels along the [100] direction, and 7.7 x 7.7 angstrom(2) channels along the [011] and [011] direction, respectively. The fluorescent, water, and methanol adsorption properties of these compounds are studied, and the results reveal that they could be potentially utilized as multifunctional materials.
