The title compound, [Tb(NO(3))(3)(C(12)H(16)N(3)O(2))(2)], was prepared from the nitroxide radical ligand 4,4,5,5-tetra-methyl--2-(pyridin-2-yl)-imidazoline-1-oxyl-3-oxide and Tb(III) nitrate. The Tb(III) ion adopts a doubly-capped square-anti-prismatic coord-ination environment defined by three chelating nitrate anions and two N,O-bidentate nitronyl nitroxide radical ligands. Weak C-H⋯O hydrogen bonds connect the molecules into a three-dimensional framework. The title structure is isotypic with the Ho analogue [Li (2012 ▶). Acta Cryst. E68, 550].
标题化合物[Tb(NO₃)₃(C₁₂H₁₆N₃O₂)₂]由氮氧自由基配体4,4,5,5-四甲基-2-(吡啶-2-基)-咪唑啉-1-氧基-3-氧化物与硝酸铽(III)制备而成。铽(III)离子采用由三个螯合硝酸根阴离子和两个N,O-双齿硝酰氮氧自由基配体定义的双帽方反棱柱配位环境。弱C-H⋯O氢键将分子连接成三维框架。标题结构与钬类似物[Li (2012 ▶). Acta Cryst. E68, 550]同型。
