Zinc and cadmium diphenate (dip, biphenyl‐2,2′‐dicarboxylate) coordination polymers containing conformationally flexible dipyridylamide ligands show diverse chain and layer topologies as determined by single‐crystal X‐ray diffraction. [Cd(dipH) 2 (bdin)] n ( 1 ) [bdin = N , N ′‐(butane‐1,3‐diyl)diisonicotinamide] shows a simple 1D zigzag chain structure. {[Cd(dip)(pdin)(H 2 O)] · 1.25H 2 O} n ( 2 ) [pdin = N , N ′‐(propane‐1,3‐diyl)diisonicotinamide] shows bilayer slabs formed by interleaving of (4,4) rectangular grid layers. {[Zn 2 (dip) 2 (3‐pna) 2 ] · 3H 2 O} n ( 3 ) (3‐pna = 3‐pyridylnicotinamide) manifests a rare 4‐connected 1D ribbon topology. {[Cd(dip)(4‐ppbp)] · 2H 2 O} n ( 4 ) [4‐ppbp = propane‐1,3‐diylbis(piperidine‐4,1‐diyl)bis(pyridin‐4‐ylmethanone)] shows a 3,5‐connected layer with (4 2 6)(4 2 6 7 8) 3,5L2 topology. {[Zn 4 (dip) 4 (H 2 O) 2 (4‐ppbp) 2 ] · 12H 2 O} n ( 5 ) exhibits 2D 3,6‐connected layers with (4 3 ) 2 (4 6 6 6 8 3 ) kgd topology featuring embedded R(8)A(2) classification 10‐membered water clusters. Compounds 1 , 4 , and 5 undergo violet or blue‐violet fluorescence upon ultraviolet irradiation. Thermal decomposition behavior of the new phases is also discussed.
