Abstract

In the title compound, [Sm(NO3)3(C24H28N4O2)], the Sm atom has tenfold coordination, built up from two imino N atoms, two deprotonated phenolic O atoms and three bidentate nitrate groups. The Sm ion is incorporated in an out-of-plane position relative to the macrocyclic ligand, which adopts a folded conformation.
