Three isomorphous Ln complexes: {[Ln₂(bt)₆(bno)(H₂O)₄]·bno}_n (bt is but-2-enoate and bno is 4,4'-bipyridyl N,N'-dioxide), with Ln = Nd, Er and Y

Abstract: The polymeric title compounds, namely catena-poly[[[di- [mu] -but-2-enoato- [kappa] ³O:O,O'; [kappa] ³O,O':O'-bis[diaquadibut-2-enoato- [kappa] O; [kappa] ²O,O'-neodymium(III)]]- [mu] -4,4'-bipyridyl N,N'-dioxide- [kappa] ²O:O'] 4,4'-bipyridyl N,N'-dioxide solvate] and the erbium(III) and yttrium(III) analogues, {[Ln₂(C₄H₅O₂)₆(C₁₀H₈N₂O₂)(H₂O)₄]·C₁₀H₈N₂O₂}_n (Ln = Nd, Er and Y), form from [Ln₂(bt)₆(H₂O)₄] dimers (bt is but-2-enoate) bridged by 4,4'-bipyridyl dioxide (bno) spacers into sets of parallel chains; these linear arrays are interconnected by aqua-mediated hydrogen bonds into broad two-dimensional structures, which in turn interact with each other though the hydrogen-bonded bridged bno solvent units. Both independent bno units in the structures are bisected by symmetry centres.

Formula: [Nd₂(C₄H₅O₂)₆(C₁₀H₈N₂O₂)(H₂O)₄]·C₁₀H₈N₂O₂, [Er₂(C₄H₅O₂)₆(C₁₀H₈N₂O₂)(H₂O)₄]·C₁₀H₈N₂O₂ and [Y₂(C₄H₅O₂)₆(C₁₀H₈N₂O₂)(H₂O)₄]·C₁₀H₈N₂O₂
