The asymmetric unit of\n 1<\/jats:bold>\n consists of one Zn\n II<\/jats:sup>\n cation that is situated on a twofold rotation axis and one chloride anion as well as one 2-aminopyrimidine ligand in general positions. The asymmetric unit of\n 2<\/jats:bold>\n is built up of one Zn\n II<\/jats:sup>\n cation, two iodide anions and two 2-aminopyrimidine ligands, all of them located in general positions. In both compounds, the metal cations are tetrahedrally coordinated by two halide anions and two 2-aminopyrimidine ligands. In compound\n 1<\/jats:bold>\n , the discrete complexes are linked by N\u2014H...Cl hydrogen bonds into layers that are further connected by weak C\u2014H...Cl interactions.
