title: catena-Poly[[(ethanol-κO)sodium(I)]-di-μ-aqua-[(rac-2'-hydr-oxy-1,1'-binaphthyl-2-yl phosphato-κO)sodium]-tri-μ-aqua].
abstract: The asymmetric unit of the polymeric title compound, [Na(2)(C(20)H(13)O(5)P)(C(2)H(6)O)(H(2)O)(5)](n), consists of two Na(I) ions, one 2'-hydr-oxy-1,1'-binaphthyl-2-yl phosphate anion, one ethanol ligand and five water molecules of crysallization. Each Na(I) ion has a distorted octa-hedral coordination geometry. The phosphate anion coordinates to one Na(I) ion and the ethanol mol-ecule coordinates to the other. The five water mol-ecules bridge the Na(I) ions, forming an inorganic chain structure along the b axis. The chains are connected by O-H⋯O hydrogen bonds into an organic-inorganic hybrid layer parallel to (001).
