摘要：In the title one-dimensional coordination polymer, j[Mn-(C_5O_5)(C_(10)H_8N_2)(H_2O)]center dot H_2O}_n, each Mn~(II) ion is seven-coordinated by four O atoms from two croconate ligands, two N atoms from a 2,2\'-bipyridine (2,2\'-bipy) ligand and one O atom from an aqua ligand. The croconate ligand bridges the Mn~(II) ions in a bis-bidentate chelation mode, forming an extended [Mn(C_5O_5)]_n chain running parallel to the  direction, with the lipophilic 2,2\'-bipy ligands lying along one side and the hydrophilic water molecules along the opposite side. Coordinated water and solvent water molecules are arranged in the hydrophilic layer, which is characterized by O-H...O hydrogen bonds between croconate ligands. Meanwhile, 2,2\'-bipy ligands from adjacent chains partially overlap and exhibit n-n interactions to form a lipophilic layer. The hydrophilic and lipophilic layers are arranged alternately to build a layer structure.
