We discuss the synthesis and characterization of coordination polymers with threaded, interpenetrated, and self-penetrated topologies based on short chain dicarboxylate ligands and hydrogen-bonding capable dipyridyl ligands such as 4-pyridylisonicotinamide (4-pina), 3-pyridylisonicotinamide (3-pina), and bis(4-pyridylmethyl) piperazine (bpmp). {[Cu2(ox)2(bpmp)]�6H2O}n (ox = oxalate) shows a 4,4-connected binodal net with an unprecedented self-penetrated (5383)2(5482) topology, with antiferromagnetic coupling observed within [Cu2(ox)2]n layer motifs. {[Mn(H2O)4(bpmp)][Mn2(oxalate)3]�5H2O}n possesses [Mn(H2O)4(bpmp)]n2n+ chains threaded through parallel [Mn2(oxalate)3]n2n� honeycomb layers in a very rare example of threaded-loop 1D + 2D -> 3D polyrotaxane interpenetration (see figure). Its magnetic properties show a superposition of antiferromagnetic coupling within the honeycomb layers and isolated spins within the chains. [Cu2(Hdmmal)2(dmmal)(4-pina)2]n (dmmal = dimethylmalonate) displays a self-penetrated 5-connected uninodal net with 42678 topology, while {[Cu2(dmmal)2(3-pina)2]�9.5H2O}n manifests a 3-fold interpenetrated diamondoid net with tetrameric cluster nodes with incipient voids containing water molecule pipes.
