Abstract: The asymmetric unit of the polymeric title compound, [Na₂(C₂₀H₁₃O₅P)(C₂H₆O)(H₂O)₅]_n, consists of two Na^I ions, one 2'-hydroxy-1,1'-binaphthyl-2-yl phosphate anion, one ethanol ligand and five water molecules of crysallization. Each Na^I ion has a distorted octahedral coordination geometry. The phosphate anion coordinates to one Na^I ion and the ethanol molecule coordinates to the other. The five water molecules bridge the Na^I ions, forming an inorganic chain structure along the b axis. The chains are connected by O-HO hydrogen bonds into an organic-inorganic hybrid layer parallel to (001).
