(Acetone-2κO){μ-6,6′-dimeth­oxy-2,2′-[propane-1,2-diylbis(nitrilo­methyl­idyne)]diphenolato-κ81:2O 6,O 1,O 1′,O 6′:O 1,N,N′,O 1′}tris(nitrato-1κ2 O,O′)copper(II)terbium(III)

In the title heteronuclear complex, [CuTb(C(19)H(20)N(2)O(4))(NO(3))(3)(CH(3)COCH(3))], the Cu(II) ion is five-coordinated by two O and two N atoms from the 6,6'-dimeth-oxy-2,2'-[propane-1,2-diylbis(nitrilo-methyl-idyne)]diphenolate ligand (L) and an O atom from the acetone mol-ecule 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 CH(2)-CH-CH(3) fragment is disordered over two conformations, with refined occupancies of 0.725 (11) and 0.275 (11).
