Three isotypic rare earth complexes, catena ‐poly[[aquabis(but‐2‐enoato‐κ 2 O , O ′)yttrium(III)]‐bis(μ‐but‐2‐enoato)‐κ 3 O , O ′: O ;κ 3 O : O , O ′‐[aquabis(but‐2‐enoato‐κ 2 O , O ′)yttrium(III)]‐μ‐4,4′‐(ethane‐1,2‐diyl)dipyridine‐κ 2 N : N ′], [Y 2 (C 4 H 5 O 2 ) 6 (C 12 H 12 N 2 )(H 2 O) 2 ], the gadolinium(III) analogue, [Gd 2 (C 4 H 5 O 2 ) 6 (C 12 H 12 N 2 )(H 2 O) 2 ], and the gadolinium(III) analogue with a 4,4′‐(ethene‐1,2‐diyl)dipyridine bridging ligand, [Gd 2 (C 4 H 5 O 2 ) 6 (C 12 H 10 N 2 )(H 2 O) 2 ], are one‐dimensional coordination polymers made up of centrosymmetric dinuclear [ M (but‐2‐enoato) 3 (H 2 O)] 2 units ( M = rare earth), further bridged by centrosymmetric 4,4′‐(ethane‐1,2‐diyl)dipyridine or 4,4′‐(ethene‐1,2‐diyl)dipyridine spacers into sets of chains parallel to the [20] direction. There are intra‐chain and inter‐chain hydrogen bonds in the structures, the former providing cohesion of the linear arrays and the latter promoting the formation of broad planes parallel to (010).
