The structure of the title compound (C 9 H 13 NO 2 NaP · 3 H 2 O) (Toldimfos Na · 3 H 2 O) has been determined at room temperature. The crystals are monoclinic, a = 38.15(2) Å, b = 4.940(3) Å, c = 14.510(8) Å, β = 109.58(4)°, V = 2576(3) Å 3 , Z = 8, D calc = 1.419 g cm —3 , space group C 2/ c . The structure was solved by direct methods and refined by full‐matrix least‐squares method (MoK α radiation; R = 0.061). Indexed powder diffraction pattern for the drug is also reported.
