The title complex was obtained by the treatment of copper(II) acetate monohydrate with the Schiff base in water/methanol (1:3). The first two reactants were stirred for 2 h, and the mixture was stirred for another 3 h after the addition of europium (III) nitrate hexahydrate. The reaction mixture was filtered; diethyl ether was allowed to diffuse slowly into the solution of the filtrate. Single crystals were obtained after several days. Analysis calculated for for C17H17Cu1Eu1N5O12: C 29.22, H 2.45, N 10.02%; found: C 29.38, H 2.38, N 10.00%.
H atoms bound to C atoms were placed in calculated positions and treated as riding on their parent atoms, with C—H = 0.93 Å (aromatic C), C—H = 0.97 Å (methylene C), and with Uiso(H) = 1.2Ueq(C) or C—H = 0.96 Å (methly C) and with Uiso(H) = 1.5Ueq(C). The H atoms of hydroxy were initially located in a difference Fourier map but they were treated as riding on their parent atoms with O—H=0.85 Å, Uiso(H) = 1.5Ueq(O) In complex (I), the diaminopropane is disordered and was refined with a split model over two positions, and with an occupancy of 0.72 (2) for C8, C9, and 0.28 (2) for C8', C9'.
As shown in Fig. 1, the tetradentate Schiff base ligand links Cu and Eu atoms into a dinuclear complex through two phenolate O atoms. The EuIII centre in (I) is nine-coordinated by two O atoms from the ligand, six O atoms from three nitrate and one O atoms from the methanol, which is similar with the bonding reported for another copper-lanthanum complex of the same ligand (Kahn et al., 2000). The CuII center is five-coordinate by two N atoms, two O atoms from the ligand and one nitrato oxygen of neighboring dinuclear unit in a square-pyramidal geometry.
See Kahn et al. (2000) for a similar copper–lanthanum complex of the same Schiff base.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

As shown in Fig. 1, the tetradentate Schiff base ligand links Cu and Eu atoms into a dinuclear complex through two phenolate O atoms. The EuIII centre in (I) is nine-coordinated by two O atoms from the ligand, six O atoms from three nitrate and one O atoms from the methanol, which is similar with the bonding reported for another copper-lanthanum complex of the same ligand (Kahn et al., 2000). The CuII center is five-coordinate by two N atoms, two O atoms from the ligand and one nitrato oxygen of neighboring dinuclear unit in a square-pyramidal geometry.
