Abstract
Crystals of (-)-2-bromosuccinamic acid (C4H6O3NBr) are orthorhombic, with space group P212121 and lattice parameters a=7.70, b=9.23, c=8.88 A, containing four molecules in the unit cell. The structure was solved by the heavy atom method coupled with three-dimensional Fourier and difference Fourier synthese. The refinement was carried out by the full-matrix least-squares calculations. The final (R) value was 0.15. The absolute configuration was established to be (S) (-) by the anomalous dispersion method. The molecular and crystal structure were also discussed.
