Abstract

In the title compound, [Nd(NO3)4(C18H15N4O2)(C18H14N4O2)], the NdIII centre is located on a twofold axis and exhibits a ten-coordinated distorted bicapped square-anti­prismatic geometry. The pyridinium NH H atom is disordered over the two ligands. Adjacent mononuclear clusters are linked through N—H⋯O and N—H⋯N hydrogen-bonding inter­actions, generating layers in the (102) plane.
