4,5,6-Triamino-2-(methylsulfanyl)pyrimidine: π-stacked hydrogen-bonded sheets of R22(8), R22(10) and R 66(32) rings

Abstract

In the title compound, C5H9N5S, the three independent C - NH2 units are all somewhat pyramidal. The molecules are linked by a combination of one N - H⋯S and two N - H⋯N hydrogen bonds into sheets containing three types of ring motif, viz.R 22(8), R22(10) and R 66(32), all of them centrosymmetric. Adjacent sheets are linked by a single π-π stacking interaction. © 2006 International Union of Crystallography.
