In the title complex, [Co(CO3)(NH3)4]ClO4, both the cation and anion lie on a mirror plane. The CoIII ion is coordinated by two NH3 ligands and a chelating carbonato ligand in the equatorial sites and by two NH3 groups in the axial sites, forming a distorted octahedral geometry. In the crystal, N—HO hydrogen bonds connect the anions and cations, forming a three-dimensional network.

In the crystal of the title compound, C6H9N3·C6H8O2, the 2-amino-4,6-dimethylpyrimidine and sorbic acid molecules are linked through N—HO and O—HN hydrogen bonds, which generate a cyclic bimolecular heterosynthon with an R22(8) graph-set motif. Further, two inversion-related pyrimidine molecules are base-paired via a pair of N—HN hydrogen bonds, forming a cyclic bimolecular homosynthon with a graph-set of R22(8). A discrete hetero tetrameric supramolecular unit along the b axis is formed by the fusion of two heterosynthons and one homosynthon. An aromatic π–π interaction [centroid–centroid distance = 3.7945 (16) Å] is observed between these tetrameric units.
