title: 2-Chloro-6-methyl-pyrimidin-4-amine.
abstract: In the crystal structure of the title compound, C5H6ClN3, mol-ecules are linked by pairs of N-H⋯N hydrogen bonds, forming inversion dimers. These dimers are linked via N-H⋯N hydrogen bonds, forming a two-dimensional network lying parallel to (100). Inversion-related mol-ecules are also linked via a slipped π-π inter-action, with a centroid-centroid distance of 3.5259 (11) Å, a normal separation of 3.4365 (7) Å and a slippage of 0.789 Å.
