Comment top

Diamine derivatives are potentially multidentate ligands. we have recently reported the crystal structure (C18H24O2N4) (II) (Xia et al., 2006) which is the ligand of the title compound and two complexes [Ce(C18H22N2O4)2] (III) (Liu et al., 2007), [Er(C18H22.5N2O4)2] (IV) (Xia et al., 2009). We report here the crystal structure of new rare earth complex (I).

In the title complex (I), the coordination environment of the Tb atom and coordination modes of (I) ligands to TbIII ion is in agreement with the complexes reported above (Fig. 1). The average bond lengths of between the terbium center oxygen atoms are 2.205 (7)Å and nitrogen atom are 2.616 (9) Å, longer than the 2.199 (4)Å and shorter than the 2.624 (4)Å of complexes (III), respectively, longer than those 2.203 (6)Å and longer than the 2.612 (8)Å of complexes (IV), respectively. The dihedral angles between phenyl ring (C4—C9 ring) and antother phenyl ring are 41.85 (31)°(C12—C17 ring), 47.59 (30)°(C4A—C9A ring) and 15.27 (48)°(C12A—C17A ring) [symmetry codes: (A) 1 - x, 1 - y, z].

In (I), the Tb atom is eight-coordinated by four O atoms and four N atoms from two 6,6'-dimethoxy-2,2'-(ethane-1,2-diyldiiminodimethylene)diphenol. The molecules are connected by van der Waals forces, resulting in a three-dimensional network.

Experimental top

A solution of 6,6'-dimethoxy-2,2'-(ethane-1,2-diyldiiminodimethylene) diphenol (0.328 g, 2 mmol) in ethanol (20 ml), and then a solution of Tb(NO3)3.6H2O (0.454 g, 1 mmol) in ethanol (10 ml) was added. The reaction mixture was stirred for 3 h in the air and then filtered. X-ray quality crystals of (I) were obtained by evaporation of an ethanol solution.

Refinement top

The space group was uniquely assigned from the systematic absences. All H atoms were located in difference Fourier maps. H atoms bonded to C, O and N atoms were treated as riding atoms, with C—H distances of 0.93 Å (aryl), 0.96 Å (methyl), 0.97Å (methylene) and N—H distances of 0.90 Å (amino), Uiso(H) = 1.2Ueq(aryl, methylene, NH) or 1.5Ueq(C) (methyl or OH). The H3C bonded to O3 is disordered and were refined with the occupancies ties to 0.5.

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.
