摘要：
The crystal structure of sodium oxamate, NaC2O3NH2, has been determined from synchrotron pow der diffraction data. First Guinier-Johannson photographs have been taken to derive the unit cell. Grid search and Rietveld refinement have been used to determine the structure. The crystal structure is monoclinic, P2(1)/c, Z=4, a = 3.5513(1) Angstrom, b = 5.2561(2) Angstrom, c = 20.4451(8) Angstrom, beta = 99.329(2)degrees and V= 376.58 Angstrom (3). The final R-p value obtained with Rietveld refinement was 6.5%.
