(Acetone-2κO){μ-6,6′-dimethoxy-2,2′-[propane-1,2-diylbis(nitrilomethylidyne)]diphenolato-κ81:2O6,O1,O1′,O6′:O1,N,N′,O1′}tris(nitrato-1κ2O,O′)copper(II)terbium(III)

In the title heteronuclear complex, [CuTb(C19H2ON2O4)-(NO3)(3)(CH3COCH3)], the Cu-II ion is five-coordinated by two O and two N atoms from the 6,6'-dimethoxy-2,2'[propane-1,2-diylbis(nitrilomethylidyne)]diphenolate ligand (L) and an O atom from the acetone molecule in a square-pyramidal geometry. The Tb-III ion is ten-coordinated by six O atoms from three chelating nitrate ligands and four O atoms from the L ligand. In L, the CH2-CH-CH3 fragment is disordered over two conformations, with refined occupancies of 0.725 (11) and 0.275 (11).
