A new family of coordination polymers has been synthesized using cobalt or zinc, 4,4'-bipyridine (4,4'-bpy), and the perfluorinated dicarboxylates tetrafluoroterephthalate (tftpa), tetrafluorophthalate (tfpha), tetrafluoroisophthalate (tfipa), and tetrafluorosuccinate (tfsuc). These materials form under similar conditions and all display similar octahedral metal coordination environments despite significant differences in their structures. Compounds 1, M(4,4'-bpy)(tftpa)(H2O)2 (M = Co, Zn), and 2, M(4,4'-bpy)(tfpha)(H2O)2 (M = Co, Zn) are two-dimensional layered structures. Compounds 3, Co(4,4'-bpy)(tfsuc)(H2O)2 and 4, M(4,4'-bpy)(tfipa)(H2O)2 (M = Co, Zn) display three-dimensional connectivity built up from two types of interconnected chains.
