Ce(III)-based frameworks : from 1D chain to 3D porous metal-organic framework Ghent University
The reaction of pyridine-2,4-dicarboxylic acid (2,4-H-2 pydc) with Ce(NO3)(3)center dot 6H(2)O, by applying only minor changes to the reaction conditions, generated a series of new one-, two-, and three-dimensional (1D, 2D, and 3D) coordination polymers, namely, [Ce(pydc)(Hpydc)-(H2O)(4)](n) (1), [Ce(pydc)(Hpydc)(H2O)(2)](n), (2), and {[Ce-3(pydc)(4)-(H2O)(2)NO3]center dot 4H(2)O}(n) (3). The ancillary ligand interaction as well as the reaction ...
