Two complexes with formulas [Ni(bpndc)(bpe)] n · 4 n H 2 O ( 1 ) and [Co(bpndc) (bpy) 1.5 ] n · 0.25 n (bpy) · 0.25 n H 2 O ( 2 ) (H 2 bpndc = benzophenone‐4,4′‐dicarboxylic acid, bpe = 4,4′‐bipyridinediethene, bpy = 4,4′‐bipyridine) were synthesized and characterized. In complex 1 , each bpndc ligands adopt bis(monodentate) modes, and Ni II ions are bridged by bpndc and bpe ligands into a 3D CdSO 4 ‐like porous metal‐organic framework with channels. But triple interpenetration occurs. In complex 2 , each bpndc ligands adopt tridentate modes, and Co II ions are linked by bpndc and bpy ligands into 2D bilayer structures with the Schläfli symbol of (4 8 .6 2 ). Each bilayer is bicatenated in a parallel fashion by two other bilayers, which results in the formation of a 2D→3D polycatenation network.
