Abstract

In the title compound, [Gd(NO3)3(C10H12N2O)2]·2C2H5OH, the GdIII ion and one nitrate anion are located on a twofold rotation axis. The GdIII ion is ten-coordinated by two N and two O atoms from two bidentate 3-(N,N-dimethylamino)-1-(2-pyridyl)prop-2-en-1-one) ligands and six O atoms from three nitrate anions in a distorted bicapped square-antiprismatic geometry. In the crystal, the components are linked by O—H⋯O hydrogen bonds. The ethanol solvent molecule is disordered over two positions in a ratio 0.615 (16):0.385 (16).
