Abstract

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 \( \bar 1 \), Z = 1, ρcalcd = 1.375 mg/m3, R = 0.0316. The environment of the cobalt atom is distorted octahedral formed by two oxygen atoms of two carboxylate groups of benzoate, two oxygen atoms of waters and two nitrogen atoms from two pyridyl nitronyl nitroxide molecules.
