| Abstract: Synthesis, crystal structure and absolute configuration for title compounds are reported in this paper. The crystal structure is determined by three dimensinal X-ray data collected by Nicolet R3 four circle dif-fraetometer. The crystal is orthorhombic with space group D2P212121, a=12.587(3), b = 14.166(3), c= 25.652(14)Å, V = 4574.2Å3,z = 4. The crystal structure was solved by Patterson method and difference Fourier syntheses. 542 positional and thermal parameters were refined by block least square refinement for nonhydrogen atoms. The final R factor is 0.074.The anomalous dispersion of Co (Ⅲ) (f = 3.068) was used to determine the absolute configurations for title compounds. Co (Ⅲ) takes d2sp3 hybrid and distorted octahedron configuration. |
