摘要
Eight new coordination polymers have been synthesized from transition metal cations, 2,2′-bipyridine (2,2′-bpy), and the perfluorinated dicarboxylates tetrafluoroterephthalate (tftpa), tetrafluoroisophthalate (tfipa), and tetrafluorosuccinate (tfsuc). This family of materials displays a striking degree of structural diversity when considering the fact that all are synthesized under identical thermodynamic and kinetic parameters. Of the eight materials, three contain three-dimensional connectivity: Co2(2,2′-bpy)2(tftpa)2(H2O) (1), Mn2(2,2′-bpy)2(tftpa)2(H2O) (2), and Cu(2,2′-bpy)(tfsuc)·0.5H2O (6). Two materials are two-dimensional layered structures: Mn(2,2′-bpy)(tfipa)·0.5H2O (3) and Cu(2,2′-bpy)(tfipa) (5). Two display one-dimensional chain structures: Cu(2,2′-bpy)(tfipa) (4) and Cu(2,2′-bpy)(tfsuc)(H2O)·H2O (7). Lastly, Zn(2,2′-bpy)(tfipa)(H2O) (8) is a discrete zero-dimensional molecular complex.
