A novel complex [Na(NIT-1-MeBzIm)3]ClO4 (NIT-1-MeBzIm=2-{2-[(1-methyl)benzimidazolyl]}-4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide) has been prepared and structurally characterized by elemental analysis, IR spectra and X-ray diffraction methods. The title complex crystallizes in Trigonal,space group P-3, Z= 2. Crystal data: C45H57ClN12NaO10, Mr=984.47, a=13.9411(8), b=13.9411(8), c=14.8622(16) (A), γ= 120°,V= 2501.5(3) (A)3, Dc =1.307g/cm3, μ(MoKα) =0.152 mm-1, F(000) =1038, R=0.0637, wR =0.1813, for 1957 observed reflections with Ⅰ＞2σ(Ⅰ). X-ray analysis reveals that Na(I) ion is six-coordinated with three NIT-1-MeBzIm radicals. As we known, the coordinated way of three radicals coordinating to Na(I) ion by chelated way in main group is the first example.
