C32 H46 N2 O 8，Mr = 586.73，m.p.458 -460 K，单斜晶系，P2（1），a = 9.187（2），B = 14.979（3），c = 11.474（2）A，β = 104.09（2）度，V = 1531.5（9）A3，Z = 2，D chi = 1.27 g cm-3，λ（Cu K α）= 1.5418 A，mu = 7.1 cm-1，F（000）= 632，室温，R = 0.039，wR = 0.053，对于3077个观察到的反射[I大于3 sigma（I）]。氨乙基C（21）原子是无序的。在O（1）-H（O 1）和N（1）原子之间以及O（3）-H（O3）和O（4）之间存在分子内氢键，稳定了环A和D所采用的船形构象。
C32H46N2O8, Mr = 586.73, m.p. 458-460 K, monoclinic, P2(1), a = 9.187 (2), b = 14.979 (3), c = 11.474 (2) A, beta = 104.09 (2) degrees, V = 1531.5 (9) A3, Z = 2, D chi = 1.27 g cm-3, lambda(Cu K alpha) = 1.5418 A, mu = 7.1 cm-1, F(000) = 632, room temperature, R = 0.039, wR = 0.053 for 3077 observed reflections [I greater than 3 sigma(I)]. The aminoethyl C(21) atom is disordered. There is an intramolecular hydrogen bond between O(1)--H(O1) and N(1) atoms, and between O(3)--H(O3) and O(4), stabilizing the boat conformations adopted by the rings A and D.
