Crystal structure of 4,6-dichloro-5-methylpyrimidine

Abstract

The title compound, C5H4Cl2N2, is essentially planar with an r.m.s. deviation for all non-H atoms of 0.009 Å. The largest deviation from the mean plane is 0.016 (4) Å for an N atom. In the crystal, molecules are linked by pairs of C—H...N hydrogen bonds, forming inversion dimers, enclosing an R22(6) ring motif.
