Abstract

In the monomeric dinuclear title complex, [CuSm(C20H22N2O4)(NO3)3], the four-coordinate CuII ion has a square-planar geometry involving two O atoms and two N atoms of the deprotonated Schiff base ligand. The SmIII ion is ten-coordinate, chelated by four O donor atoms of the Schiff base and two O atoms each from three bidentate nitrate groups, one of which is disordered over two sites in a 0.55 (7):0.45 (7) ratio.
