    • A pale yellow crystal of dimensions 0.50 x 0.80 x 0.04 mm was used for X-ray diffraction on a MAC DIP-2030K diffractometer with Mo Ka radiation and graphite monochromator by maximum 2θ value of 50.0°. The total number of independent reflections was 3714, of which 3306 were observed, F|2 ≥ 2σ(|F|2), Crystal data: molecular formula (C20H31O2N 1)· (H2O)2.5, M, 317.48 (excluded the solvent, orthorhombic system, space group: C2, a, 23.563(1) Å, b, 8.728(1) Å c, 19.397(1) Å, β, 90.48(1)°, V, 3989.0(5) Å3, Z, 8, d, 1.132 g/cm3. The structure was solved by the direct method (SHELXs-9713) and expanded using difference Fourier techniques, refined by the full-matrix least-squares method NOMCSDP14, Hydrogen atoms were fixed at
