2,6-Dimethylpyrazine at 20 K: a neutron-diffraction study

E. Kaiser-Morris, B. Nicolaï, A. Cousson, W. Paulus and F. Fillaux

Abstract: Single crystal neutron diffraction techniques are used to determine the crystal structure of 2,6-dimethylpyrazine (DMP), C₆H₈N₂, at 20 K. The space group is P2₁/a with Z = 4, as at room temperature. The methyl groups are ordered. There are two crystallographically inequivalent methyl groups in the unit cell.
