Abstract
Melamine, C3N6H6, or 2,4,6‐triamino‐s‐triazine, is monoclinic, space group P21/a, with a = 10.537(2), b = 7.477(1), c = 7.275(1) Å, β = 112°9′(1), and Z = 4. Data were collected with an automatic diffractometer using crystal monochromated MoKα radiation. In addition to the usual spherical free atom model with anisotropic thermal parameters, least‐squares refinements were made with one‐center and two‐center generalized scattering factors. The aspherical distortions found are chemically reasonable and in most cases have the symmetry of the molecule although the symmetry is not crystallographically required. Addition of the generalized scattering factor parameters produced a significant improvement between observed and calculated intensities but made no significant change in the molecular geometry.
