In the title heteronuclear ZnII–SmIII complex, [SmZn(C18H18N2O4)(NO3)3(CH3CH2OH)], with the hexadentate Schiff base compartmental ligand N,N′-bis(3-methoxysalicylidene)ethylenediamine (H2L), the SmIII and ZnII ions are triply bridged by two phenolate O atoms from the Schiff base ligand and one nitrate anion. The five-coordinate ZnII ion is in a square-pyramidal geometry formed by the donor centers of two imine N atoms, two phenolate O atoms and one of the bridging nitrate O atoms. The SmIII center is in a ten-fold coordination of O atoms, involving the phenolate O atoms, two methoxy O atoms, one ethanol O atom, and two O atoms from two nitrate anions and one from the bridging nitrate anion. In the crystal, intermolecular O—H⋯O and C—H⋯O interactions generate a layer structure extending parallel to (101).

H2L was prepared by the 2:1 condensation of 3-methoxysalicylaldehyde and ethylenediamine in methanol. Complex (I) was obtained by the treatment of zinc(II) acetate dihydrate (0.188 g, 1 mmol) with H2L(0.328 g, 1 mmol) in ethanol solution (80 ml) under reflux for 3 h and then for another 3 h after the addition of samarium(III) nitrate hexahydrate(0.444 g, 1 mmol). The reaction mixture was cooled and the resulting precipitate was filtered off, washed with diethyl ether and dried in vacuo. Single crystals of (I) suitable for X-ray analysis were obtained by slow evaporation at room temperature of a ethanol solution. Analysis calculated for C20H24N5O14SmZn: C 31.03, H 3.12, N 9.05, Sm 19.42, Zn 8.45%; found: C 31.10, H 2.98, N 8.99, Sm 20.01, Zn 8.40%. IR(KBr, cm-1): 1640(C=N), 1386,1490(nitrate).
The H atoms were positioned geometrically and treated as riding on their parent atoms, with C—H distances of 0.97 (methylene), 0.96 Å (methyl) and 0.93 Å (aromatic), and with Uiso(H) = 1.5Ueq(C) for methyl H atoms and 1.2Ueq(C) for other H atoms. The hydroxyl H atom, H14s, was located in a difference Fourier map and the O14—H14s was restrained to 0.88 Å.

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. |

The potential applications of trivalent lanthanide complexes as contrast agent for magnetic resonance imaging and stains for fluorescence imaging have prompted considerable interest in the preparation, magnetic and optical properties of 3 d-4f hetorometallic dinuclear complexes (Baggio et al., 2000; Caravan et al., 1999; Edder et al., 2000; Knoer et al., 2005). we report here the synthesis and X-ray crystal structure analysis of the title complex, (I), a new ZnII—SmIII complex with salen-type Schiff base N,N'-bis(3-methoxysalicylidene) ethylenediamine(H2L).
Complex (I) crystallizes in the space group P21/n, with zinc and samarium triply bridged by two phenolate O atoms provided by a salen-type Schiff base ligand and one nitrate. The inner salen-type cavity is occupied by zinc(II), while samarium(III) is present in the open and larger portion of the dinucleating compartmental Schiff base ligand.
The SmIII center has a decacoordination environment of O atoms, involving the phenolate O atoms, two methoxy O atoms, one ethanol O atom, two O atoms from two nitrates and one from the bridging nitrate. The five kinds of Sm—O bond distances are significantly different, the longest being the Sm—O(methoxy) separations and the shortest being the Sm—O5(bridging nitrate).
The ZnII is in a square-pyramidal geometry and is five-coordinated by two imine N atoms, two phenolate O atoms and one of the bridging nitrate O atoms.
Adjacent molecules are held together by typical O—H···O hydrogen bonds and weak C—H···O interactions. these link the molecules into a two-dimensional layer structure(Fig 2).
