Abstract: 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-HO hydrogen bonding to the complex cation. Additionally, the complex cations form one-dimensional chains along  by hydrogen bonding of the NH group of an imidazole ring to the picolinate group of a neighbouring complex cation.
