In the title compound, [Tb(CH₃CN)(C₂₃H₂₆O₈)(H₂O)₃](ClO₄)₃, the Tb³⁺ atom is eight-coordinated by one N atom of an acetonitrile molecule, three water O atoms and four ligand O atoms. The Tb³⁺ atom is located on one side of the macrocycle and the carbonyl oxygen coordinated to the terbium [Tb1—O1= 2.210 (3) Å] is bent out of the xanthone plane by 0.514 (3) Å. The geometry around terbium is a distorted two-capped trigonal prism.

The xanthone derivatives show good properties in pharmacology and selectively recognition of guest species. A series of alkali metal and alkaline earth metal complexes derived from xanthone-crown ether have been synthesised and studied as fluorescent sensors. However, the rare earth complexes with novel structure derived from xanthone-crown ether have rarely been reported. Herein, we report the synthesis and structure of the title compound, 3-ethoxy-1,8-(3,6,9-trioxaundecane-1,11-diylioxy)xanthone terbium(III) perchlorate. The Tb³⁺ is located on one side of the macrocycle and the carbonyl oxygen coordinated to the terbium (Tb1—O1= 2.210 (3) Å) is bent out of the xanthone plane as to increase the coordination space. Tb³⁺ is eight coordinated by one nitrogen of CH₃CN (Tb1—N1= 2.467 (5) Å), three oxygens from three water molecule (Tb1—O21= 2.412 (4) Å, Tb1—O22= 2.391 (4) Å, Tb1—O23= 2.359 (5) Å) and four ligand oxygens (Tb1—O1= 2.210 (3) Å, Tb1—O3= 2.467 (4) Å, Tb1—O4= 2.442 (4) Å, and Tb1—O5= 2.477 (4) Å) (Fig. 1 and Table 1). The selected bond angles around Tb³⁺ were listed as following: O1—Tb1—O3 = 105.85°, O1—Tb1—O4 = 148.44°, O1—Tb1—O5 = 106.73°, O3—Tb1—O4 = 66.29°, O4—Tb1—O5 = 66.27°, O3—Tb1—O5 = 130.40°, O21—Tb1—O22 = 132.39°, O21—Tb1—O23 = 141.50°, O22—Tb1—O23 = 75.57°. Geometry around terbium is a distorted two-capped trigonal prism.

Special details top

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds 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.
