Crystal structure of bis-(acetato-κ²O,O')di-aqua-[1-(pyridin-2-yl-methyl-idene-κN)-2-(pyridin-2-yl-κN)hydrazine-κN¹]terbium(III) nitrate monohydrate.

ABSTRACT: In the title compound, [Tb(C₂H₃O₂)₂(C₁₁H₁₀N₄)(H₂O)₂]NO₃·H₂O, the Tb³⁺ ion is nine-coordinated in a distorted tricapped trigonal-prismatic geometry by the three N atoms of the tridentate 1-(pyridin-2-yl-methyl-idene)-2-(pyridin-2-yl)hydrazine ligand, four carboxyl-ate O atoms of two chelating acetate groups and two O atoms of the coordinating water mol-ecules. The organic hydrazine ligand is disordered over two orientations with a refined occupancy ratio of 0.52 (3):0.48 (3). All bond lengths in the coordination environment of the Tb³⁺ ion are slightly larger than those observed in the isostructural Y³⁺ and Er³⁺ complexes. In th
