The crystal structure of the title compound has been determined by the heavy-atom method from X-ray diffracto-meter data and refined by block-diagonal least-squares to R 0.056 for 1891 observed reflections. Crystals are monoclinic, space group P21/n, a = 19.005(4), b = 15.598(3), c = 6.913(1) Å, β = 92.34(1)°, Z = 4. The quaterpyridyl ligand is planar and coplanar with the cobalt, the inner nitrogen atoms bonding to it at a shorter distance (1.855 ± 0.005) than the outer (1.97 ± 0.01 Å). Co-OH2 is 2.067(5) and Co-S 2.244(2) Å. The nitrate ion is disordered.
