A new Cd(II) complex with four nitronyl nitroxide radicals [Cd(NIT4Py)4Cl2] (NIT4Py = 2-(4΄-pyridinyl)-4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide) has been synthesized and structurally characterized by X-ray diffraction analysis. It crystallizes in triclinic, space group Pwith a = 7.2441(4), b = 13.6964(8), c = 13.7354(8) Å, α = 89.8610(10), β = 77.9180(10), γ = 87.2250(10)°, V = 1331.01(13) Å3, C48H64CdCl2N12O8, Mr = 1120.41, Z = 1, Dc = 1.398 g/cm3, μ(MoKα) = 0.573 mm–1, F(000) = 582, S = 1.043, the final R = 0.0257 and wR = 0.0641 for 4333 observed reflections(I > 2s(I)). The title complex exists in the mononuclear-metal structures, in which each Cd(II) ion adopts a distorted octahedral geometry and is coordinated by two Cl- anions and four pyridyl-N atoms from four NIT4Py ligands. The magnetic measurements show weak antiferromagnetic interactions between the nitroxide radicals.
