Abstract
C26H43NO4 is monoclinic, P21. The unit-cell dimensions at 298(2)K are a = 6.0636(4), b = 14.2351(9), c = 14.6751(8)Å, β = 101.680(2)°, V = 1240.47(13)Å3, Dx = 1.161 g/cm3, and Z = 2. The R value is R = 0.0424 for 4545 reflections. The A, B, C, D and E rings occur in chair, half-chair, chair, half-chair and chair conformations, respectively. The molecules in the crystal are internally linked by both intra- and intermolecular O-H…O and N-H…O hydrogen bonds and four C-H…O interactions.
