A new nickl(Ⅱ) complex containing the thiazole-substituted nitroxide radical with the formula Ni(NIT2-thz) 2Cl 2(NIT2-thz=4,4,5,5-tetramethyl-2-(2′-thiazole)imidazolin-1-oxyl-3-oxide) was synthesized and its crystal structure was determined. The magnetic property analysis indicates that there is strong antiferromagnetic interactions between Ni(Ⅱ) and radical(J=-71.82 cm -1).
