catena-Poly[[(ethanol-κO)sodium(I)]-di-μ-aqua-[(rac-2′-hydroxy-1,1′-binaphthyl-2-yl phosphato-κO)sodium]-tri-μ-aqua]

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'-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-H center dot center dot center dot O hydrogen bonds into an organic-inorganic hybrid layer parallel to (001).
