Aqua­trinitrato[2,4,6-tris­(pyridin-2-yl)-1,3,5-triazine]neodymium(III) dihydrate

In the title compound, [Nd(NO3)3(C18H12N6)(H2O)]·2H2O, the Nd3+ ion is in a distorted bicapped square-anti­prismatic geometry formed by three N atoms from the 2,4,6-tris­(pyridin-2-yl)-1,3,5-triazine (TPTZ) ligand, six O atoms from the three nitrate anions and one O atom from the aqua ligand. The mol­ecules are linked by O—H⋯O and O—H⋯N hydrogen bonds. Two types of π–π stacking inter­actions occur between the TPTZ ligands of adjacent complexes [centroid-to-centroid distances = 3.760 (4) and 3.870 (3) A].
