Divalent cobalt coordination polymers containing both ortho- phenylenediacetate (ophda) and rigid dipyridyl ligands 4,4′-bipyridine (bpy) or 1,2-bis(4-pyridyl)ethylene (dpee) display different topologies depending on carboxylate binding mode, tether length, and inclusion of charged species. [Co(ophda)(H2O)(dpee)]n (1) displays a common (4,4) grid layer motif. Use of the shorter bpy tether afforded {[Co 2(ophda)2(bpy)3(H2O) 2][Co(bpy)2(H2O)4](NO 3)2·2bpy·7H2O}n (2) or [Co(ophda)(bpy)]n (3) depending on cobalt precursor. Compound 2 manifests 5-connected [Co2(ophda)2(bpy)3(H 2O)2]n pillared bilayer slabs with rare 4 862 SnS topology and entrained [Co(bpy)2(H 2O)4]2+ complex cations. The 3-D coordination polymer 3 has an uncommon 4,6-connected binodal (446 2)(446108) fsc topology, and shows ferromagnetic coupling (J = +1.5(2) cm-1) along 1-D spiro-fused [Co(OCO)2]n chain submotifs.
