Abstract: In the mononuclear title compound, [La(NO₃)₃(C₅H₅NO)₂(H₂O)₂], the La^III atom is ten-coordinate, with a coordination polyhedron made up of the O atoms of two 4-pyridone ligands, six O atoms of three O,O'-chelating nitrate groups and two water molecules, the polyhedron approximating a dodecahedron. The molecule lies on a twofold rotation axis. A three-dimensional network structure is formed by hydrogen-bonding and - stacking interactions.
