Glycine has three polymorphs, among them the 7-form crystallizes in the hexagonal space group /)31 or P32 with unit-cell dimensions a -7.037, c = 5.483/~. Its crystal structure has been determined by two-dimensional Fourier and three-dimensional least-squares methods. The dimensions of the molecule are close to those found in the other forms. The structure consists of hydrogen bonded molecular chains which are held together by lateral hydrogen bonds forming a three-dimensional network.
