Abstract: The title complex, {[Cd(NCS)₂(H₂O)₂]·2C₆H₉N₃}_n, crystalizes in the triclinic space group P $\overline 1$ . The asymmetric unit contains one 2-amino-4,6-dimethylpyrimidine molecule, a thiocyanate ion, a water molecule and a cadmium ion (site symmetry $\overline 1$ ). The cadmium ions are symmetrically doubly bridged by thiocyanate ions, leading to a polymeric chain motif. The octahedral coordination geometry of cadmium is completed by a pair of inversion-related water molecules. The 2-aminopyrimidine molecules are not coordinated to cadmium but are hydrogen-bonded to the coordinated water molecules and thiocyanate ions. There is also a pyrimidine-pyrimidine interaction via an N-HN hydrogen bond.
