Aqua[tris(2-{5-[(4-methylphenyl)diazenyl]-2-oxidobenzylideneamino}ethyl)amine]samarium(III) acetonitrile monosolvate

In the title compound, [Sm(C48H45N10O3)(H2O)]·CH3CN, the SmIII ion is coordinated by the heptadentate tris(2-{5-[(4-methylpheny)diazenyl]-2-oxidobenzylideneamino}ethyl)amine trianionic ligand and a water molecule. The resulting SmN4O4 coordination polyhedron is a distorted square antiprism. In the crystal, complex molecules are linked by O—H...O hydrogen bonds.
