catena-Poly(ethanol-κO)sodium(I)-di-μ-aqua-(rac-2′-hydr­oxy-11′-binaphthyl-2-yl phosphato-κO)sodium-tri-μ-aqua

摘要

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—H⋯O hydrogen bonds into an organic–inorganic hybrid layer parallel to (001).
