A new Nd(III) nitronyl nitroxide complex [Nd(NIT2Py)2(NO3)3] (NIT2Py = 2-(2?- pyridyl)-4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide) has been synthesized and structurally charac- terized by X-ray diffraction. It crystallizes in monoclinic, space group P21/n with a = 12.396(4), b = 11.134(4), c = 23.360(7) ?, β = 98.178(6)o, V = 3191.2(18) ?3, C24H32N9NdO13, Mr = 798.83, Dc = 1.663 g/cm3, μ(MoKα) = 1.704 mm-1, F(000) = 1612, Z = 4, the final R = 0.0425 and wR = 0.0957 for 6532 independent reflections with Rint = 0.0642 and 4552 observed reflections (I > 2σ(I)). The complex exists as discrete mononuclear molecules and the neodymium(III) ion is ten-coordinated with three bidentate nitrate anions and two radical ligands (NIT2Py) via bidentate chelating mode. The optical properties of the complex are discussed.
