Crystal structure of bis­(acetato-?2O,O?)di­aqua­[1-(pyridin-2-yl­methyl­idene-?N)-2-(pyridin-2-yl-?N)hydrazine-?N1]terbium(III) nitrate monohydrate

The Tb3+ ion is nine-coordinated in a distorted tricapped trigonal-prismatic geometry by the three N atoms of the tridentate 1-(pyridin-2-yl­methyl­idene)-2-(pyridin-2-yl)hydrazine ligand, four carboxyl­ate O atoms of two chelating acetate groups and two O atoms of the coordinated water mol­ecules. In the crystal, the complex cations are linked by pairs of O—H?O hydrogen bonds into dimers. These dimers, nitrate anions and non-coordinating water mol­ecules are joined by O—H?O and N—H?O hydrogen bonds into a three-dimensional structure.
