Single crystals of the title compound, [Co(C6H4NO2)(C18H27N6P)]NO3, were obtained from the reaction of nitrato[tris­(2-isopropyl­imidazol-4-yl)phosphane]cobalt(II) nitrate with picolinic acid in the presence of potassium tert-butoxide as base. The coordination polyhedron around the central CoII ion is about halfway between square-pyramidal and trigonal-bipyramidal geometry. In the structure, the nitrate counter-anion is connected by N—H...O hydrogen bonding to the complex cation. Additionally, the complex cations form one-dimensional chains along [010] by hydrogen bonding of the NH group of an imidazole ring to the picolinate group of a neighbouring complex cation.

In the title compound, [Mn(C13H16N6O)(CO)3](CF3O3S), the MnI atom has a slightly distorted octa­hedral geometry. The three CO ligands have C—Mn—C angles in the range 89.44 (10)–92.31 (9)°, while the three N atoms of the tripodal ligand form significantly smaller N—Mn—N angles of 82.76 (2)–85.51 (6)°. The three N atoms of the tripodal ligand and the three carbonyl ligands coordinate facially. In the crystal, the trifluoro­methane­sulfonate counter anion is connected by a medium-strength O—H...O hydrogen bond to the hydroxyl group of the manganese complex.
