A new cobalt coordination compound with nitronyl nitroxide and benzonate, Co(PyNIT)2(PhCOO)2(H2O)2, where PyNIT = 2-(p-pyridyl)-4,4′,5,5′-tetramethylimidazoline-1-oxyl-3-oxide, was synthesized and its X-ray diffraction analysis was carried out. The crystals were triclinic: a = 6.7749(4), b = 11.3472(7), c = 12.9066(8) Å, α = 87.906(1)°, β = 88.631(1)°, γ = 79.080(1)°, V = 973.45(10) Å3, space group P
