Abstract

In the title dinuclear complex, [CuGd(C20H22N2O4)(NO3)3], the CuII ion is located in the inner N2O2 cavity of the Schiff base ligand and adopts a distorted square-planar geometry. The GdIII ion is ten-coordinate being bound to ten O atoms, four from the Schiff base ligand and six from three bidentate nitrate anions. The CuII and GdIII ions are linked by two phenolate O atoms of the Schiff base ligand, with a separation of 3.5185 (9) Å.
