title: (Picolinato-κN,O)[tris(2-isopropyl-1H-imidazol-4-yl-κN)phosphane]cobalt(II) nitrate.
abstract: Single crystals of the title compound, [Co(C(6)H(4)NO(2))(C(18)H(27)N(6)P)]NO(3), were obtained from the reaction of nitrato[tris-(2-isopropyl-imidazol-4-yl)phosphane]cobalt(II) nitrate with picolinic acid in the presence of potassium tert-butoxide as base. The coordination polyhedron around the central Co(II) 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.
