Abstract:
C17H25N3O4.1/2H2O, Mr = 344.4, monoclinic, B2, a = 18.299 (6), b = 18.781 (6), c = 5.917 (3) A, gamma = 110.65 (3) degrees, V = 1902.9 (10) A3, Z = 4, Cu K alpha, lambda = 1.54178 A, mu = 0.73 mm-1, F(000) = 740, D chi = 1.202 Mg m-3, room temperature, final R = 0.048 and wR = 0.048 for all (1470) reflections. The molecules are stacked in layers along the alpha axis. There are five intermolecular hydrogen bonds.
