The crystal structure of<scp>L</scp>-alanine

Abstract

The crystal structure of L-alanine, C3H702N, has been determined and refined by analysis of complete three-dimensional diffraction data from copper X-radiation. The crystals are orthorhombic with space group P212~21 ; the unit-cell dimensions are a = 6.032, b = 12.343, c = 5.784 A. Least-squares refinement of the positional parameters of all 13 atoms and of the individual anisotropic temperature factors of the six heavy atoms, using 581 observed reflections of non-zero weight, yielded a final R index of 0.049.
