2,6-Diamino-4-chloropyrimidine–succinic acid (2/1)

Abstract

In the title 2:1 co-crystal, 2C4H5ClN4·C4H6O4 the complete succinic acid molecule is generated by a crystallographic centre of symmetry. In the crystal, pairwise O—H...N and N—H...O hydrogen bonds link the pyrimidine and succinic acid molecules, generating R 2 2(8) loops. The pyrimidine molecules are linked by pairwise N—H...N hydrogen bonds, again generating R 2 2(8) loops. Collectively, the hydrogen bonds link the components into corrugated (100) sheets. The Hirshfeld surface is presented.
