摘要

By fusing Lu_2O_3 and TeO_2 in a molar ratio of 1:3 in a CsCl flux, colorless single crystals of the lutetium(III) oxotellurate(IV) Lu_2Te_3O_9 could be obtained as first representative of the structurally so far unknown C-type for the composition M_2Te_3O_9. The title compound crystallizes triclinically in space group P1 with a = 689.67(4) pm, b = 1320.91(8) pm, c = 1450.06(9) pm, α = 110.057(3)°, β = 90.606(3)°, γ = 100.125(3)°, and Z = 6. The crystal structure contains six different Lu3+ cations in eightfold (Lu1 and Lu2: trigonal dodecahedra) and sevenfold (Lu3 and Lu6: monocapped trigonal prisms; Lu4 and Lu5: pentagonal bipyramids) oxygen coordination. These lutetium-oxygen polyhedra (d(Lu-O) = 214-274 pm) are condensed to serrated layers according to 2 ∞{[Lu6O26]34-} that are stacked along [100]. The oxotellurate(IV) partial structure consists of basically nine crystallographically independent [TeO_3]~(2-) (d(Te-O) = 184-196 pm) units connecting the above-mentioned layers to a three-dimensional framework. Strong secondary Te~(4+)???O~(2-) interactions between adjacent [TeO_3]~(2-) entities as common feature in the crystal structures of all known ternary lanthanoid(III) oxotellurates(IV) are also present in the crystal structure of Lu_2Te_3O_9. Depending upon the range of these secondary contacts taken into account, the [TeO_3]~(2-) units are linked to form one-dimensional strands (d(Te???O) = 237-272 pm) like in B-type Dy_2Te_3O_9 or even two-dimensional layers emerge (d(Te???O) = 237-285 pm).

O〜（2-）相互作用也是存在于Lu_2Te_3O_9的晶体结构中。取决于所考虑的这些二次接触的范围，[TeO_3]〜（2-）单元被链接以形成一维链（d（Te ??? O）= 237-272 pm），就像在B型中一样Dy_2Te_3O_9或什至二维层出现（d（Te ??? O）= 237-285 pm）。
