title: Bis[4,4,5,5-tetra-methyl-2-(pyridin-2-yl-κ(2)N)imidazoline-1-oxyl 3-oxide-κO]tris-(nitrato-κ(2)O,O')terbium(III).
abstract: 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].
