Abstract top

In the title heteronuclear complex, [CuSm(C19H20N2O4)(NO3)3(CH3COCH3)], the CuII ion is five-coordinated by two O and two N atoms from the 6,6'-dimethoxy-2,2'-[propane-1,2-diylbis(nitrilomethylidyne)]diphenolate ligand (L) and by an O atom from the acetone molecule in a square-pyramidal geometry. The SmIII ion is ten-coordinated by six O atoms from the three nitrate ligands and four O atoms from the L ligand. In L, the C atoms of the diaminopropane fragment are disordered over two positions in a 0.674 (10):0.326 (10) ratio.

Comment top

In continuation of our study of heteronuclear complexes of N,N'-bis(3- methoxysalicylidene)propane-1,2-diamine ligand (Sun et al., 2007, 2009), we present here the crystal structure of the title compound. As shown in Fig. 1, ligand L links Cu and Sm atoms into a dinuclear complex through two phenolate O atoms, and the SmIII centre in the complex is ten-coordinated by four oxygen atoms from L and six oxygen atoms from three nitrato ions. The CuII center is five-coordinate by two nitrogen atoms and two oxygen atoms from the ligand and one oxygen atom from acetone in a square-pyramidal geometry. The title compound is isostructural with the previous Cu—Ln complexes (Ln = Gd, Pr and Tb) (Kara et al., 2000; Sun et al., 2007, 2009) derived from the same ligand.

Experimental top

To a 1:1 MeOH/Me2CO solution (20 ml) of the Schiff ligand (0.086 g, 0.250 mmol) was slowly added an aqueous solution (8 ml) of [Cu(Ac)2H2O] (0.050 g, 0.25 mmol), after refluxing and stirring for 3 h, was slowly added a MeOH solution (10 ml) of Sm(NO3)36H2O (0.105 g, 0.25 mmol) at ambient temperature. After stirring for 5 h, red solid was collected by filtration and washed with MeOH, [CuSm(C19H20N2O4)(CH3COCH3)(NO3)3], yield 0.180 g (87%). Single crystals suitable for X-ray determination were obtained by slow diffusion of diethylether into a methanol solution of the powder sample over one week. Analysis calculated for C22H26CuN5O14Sm: C, 33.10; H, 3.28; N, 8.77; found: C, 33.01; H, 3.31; N, 8.92%.

Refinement top

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 = 0.98 Å (methylene C), C—H = 0.96 Å (methly C) and with Uiso(H) = 1.2Ueq(C). The C atoms of the diaminopropane fragment were treated as disordered over two positions with the occupancy factors refined to 0.674 (10) and 0.326 (10), respectively.

Special details top

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.
