Diaquatris(nitrato-κ2O,O′)bis(4-pyridone-κO)lanthanum(III)

In the mononuclear title compound, [La(NO3)3(C5H5NO)2(H2O)2], the LaIII 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 π–π stacking inter­actions.
