Abstract: The title compound crystallizes in orthorhombic crystal system with space group P 2_12_12_1, α=0.8983(4) nm, b=1.7538(9) nm, c=1.7603(16) nm and z=4. The crystal structure were solved by direct method. Molecular absolute configurations for two enantiomeric structures were determined by anomalous scattering of Pd~(++) for CuKα radiation. The final R factors are 0.050 for R-(+)-structureand 0.051 for S-(-)-structure.
