| 摘 要： | 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 P1 with a = 7.2441(4),b = 13.6964(8),c = 13.7354(8) ,α = 89.8610(10),β = 77.9180(10),γ = 87.2250(10)°,V = 1331.01(13) 3,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 > 2σ(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.
