摘要：
The crystal structure of [Co(NH3)(5)Br]Br-2 has been determined ab initio from the conventional X-ray powder diffraction data. The approximate structure with all 7 independent non-H atoms was solved by direct methods. The final orthorhombic unit-cell parameters after Rietveld refinement are: a=13.6927, b=10.7071, c=6.9400 Angstrom, V=1017.47 Angstrom(3), F-30=93(0.0075, 43, M-20=49, Z=4 Space group is Pnma. The structure agreement factors are: Rp=0.066, Rwp=0.090, R-F=0.041: R-B=0.042.
