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(C₁₈H_22.5N₂O₄)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 Tb^III 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.

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.
