ABSTRACT
In the title compound, [Nd(NO(3))(3)(C(18)H(12)N(6))(H(2)O)]·2H(2)O, the Nd(3+) ion is in a distorted bicapped square-anti-prismatic 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 mol-ecules are linked by O-Hâ¯O and O-Hâ¯N hydrogen bonds. Two types of π-π stacking inter-actions occur between the TPTZ ligands of adjacent complexes [centroid-to-centroid distances = 3.760â (4) and 3.870â (3)â Å].
