Two new polymeric MnII complexes, {[Mn(1,2-BDC-F4)(H2O)3](EtOH)}n (1) and [Mn(1,2-BDC-F4)(H2O)2(DMF)]n (2), have been prepared from the reaction of MnII acetate with 3,4,5,6-tetrafluoro-benzene-1,2-dicarboxylic acid (1,2-H2BDC-F4) using different solvents, and characterized by elemental analysis, IR spectroscopy, thermogravimetric (TG) analysis, and single-crystal X-ray structure analysis. Both complexes crystallize in the triclinic space group P1̅ and have similar one-dimensional double chain structures, consisting of a unique arrangement of 8-membered and 14-membered rings. The effects of solvent as ligand and/or guest on the
self-assembly processes of the supramolecular networks and on their photoluminescence properties in the solid state are discussed.
