Abstract top

In the title compound, [Gd(C15H11O2)3(C17H18N2)], the GdIII atom is coordinated by six O atoms from three [beta]-diketonate ligands and two N atoms from a chiral ligand LS,S-(+)-7,7-dimethyl-3-(2-pyridyl)-5,6,7,8-tetrahydro-6,8-methanoisoquinoline, in a coordination geometry best described as distorted square-antiprismatic.

Comment top

In the coordination chemistry field, chiral ligands play a key role in designing noncentrosymmetric complexes. In particular, many useful physical properties such as ferroelectricity, piezoelectricity, magneto-chiral dichroism and second harmony generation etc. are only based on noncentrosymmetric crystal lattices (Kaneko et al., 2006; Kimura et al., 2003). An effective and facile method to prepare such kind of complexes is the introducing of chiral motifs in molecule. Based on this strategy, as a continuance of our research (Li et al., 2007), we employed a chiral ligands LS,S, (+)7,7-dimethyl-3-(2-pyridyl)-5,6,7,8-tetrahydro-6,8-methanoisoquinoline, to react with Gd(dbm)3.2H2O (dbm = dibenzoylmethanide), and an enantiomerically pure compound with formula Gd(dbm)3LS,S was obtained.

As shown in Fig. 1, the title compound contains three β-diketonate ligands, a chiral bipyridine derivative ligand and a GdIII atom, which is isostructural with our previously reported Eu(dbm)3LS,S (Li et al., 2007). The GdIII atom is coordinated by six O atoms from three β-diketonate ligands and two N atoms from a chiral bipyridine derivative in an eight-coordinated distorted square-antiprismatic environment. The Gd—O bond distances rang from 2.338 (4) to 2.371 (5) Å, while two Gd—N bond distances are 2.587 (4) and 2.601 (3) Å. The two square planes defined by O5, O6, N1, N2 (top face) and O1, O2, O3, O4 (bottom face) (Fig.2) with mean deviations of 0.121 (3) and 0.063 (3) Å, respectively, make a dihedral angle of 1.40 (1)°. The title compound crystallizes in the chiral space group P21 and the chirality is dominated by two chiral centers (C57 and C58) of bipyridine derivative.

Experimental top

The chiral ligand LS,S was prepared by the documented procedures (Hayoz & Zelewsky, 1992) and Gd(dbm)3.2H2O was synthesized according to literature method (Carles & Ohlmann, 1965). A solution of Gd(dbm)3.2H2O (0.086 g, 0.1 mmol) in ethanol was added to a solution of LS,S in acetone. The mixture was kept at room temperature. Yellow single crystals of the title compound, suitable for X-ray analysis, were obtained in 79% yield by slow evaporation of the solvent over two weeks. Analysis calculated for C62H51GdN2O6: C 69.00, H 4.77, N 2.60%; found: C 71.02, H 4.67, N 2.86%.

Refinement top

H atoms were positioned geometrically and treated as riding atoms, with C—H = 0.93 (aromatic), 0.98 (tertiary), 0.97 (methylene) and 0.96 (methyl) Å and with Uiso(H) = 1.2(1.5 for methyl)Ueq(C). The highest residual electron density was found 0.92 Å from Gd1 and the deepest hole 0.52 Å from H55.
