Crystals of sodium trihydrogen-1,4-benzenediphosphonate, Na[H(3)bdp], were prepared from the addition of aqueous sodium hydroxide to an acidified solution of 1,4-benzenediphosphonic acid (H(4)bdp). These were shown by X-ray crystallography to crystallize in the space group P (1) over bar, with cell parameters a = 5.7500(3) , b = 7.9180(5) , c = 10.4420(6) , alpha = 80.398(3)A degrees, beta A = 76.844(4)A degrees and gamma A = 81.389(4)A degrees. The crystal structure revealed that the title compound forms a coordination network in which sodium-phosphonate sheets are pillared by the benzene rings into a three-dimensional structure.
