  Monothiocarbonate derivatives of diorganotellurium(IV), R₂Te[SCO₂R′]₂, and R₂TeX[SCO₂R′], where R = Me, Ph; R′ = Me, i-Pr; X = Cl, Br, and I, have been prepared and characterized by vibrational and ¹H, ¹³C, and ¹²⁵Te NMR spectroscopy. Me₂Te[SCO₂(i-Pr)]₂ (2): P2₁/n (No. 14) with cell parameters a = 6.942(6) Å, b = 25.599(3) Å, c = 9.404(6) Å, β = 94.48(6)°, V = 1666(1) ų, Z = 4, R = 0.0648, R_w = 0.0624; Ph₂Te[SCO₂(i-Pr)]₂ (4): P2₁/n (No. 14) with a = 12.360(4) Å, b = 12.277(3) Å, c = 15.066(3) Å, β = 102.82(2)°, V = 2229.1(9) ų, Z = 4, R = 0.0368, R_w = 0.0312; Me₂TeCl[SCO₂Me] (5); P2₁/c (No. 14) with a = 5.193(2) Å, b = 18.118(4) Å, c = 9.613(5) Å, β = 91.31(6)°, V = 904.2(6) ų, Z = 4, R = 0.0396, R_w = 0.0361; and Me₂TeBr[SCO₂(i-Pr)] (8): P2₁/n (No. 14) with a = 11.701(2) Å, b = 6.250(2) Å, c = 16.152(2) Å, β = 98.43(1)°, V = 1168.4(4) ų, Z = 4, R = 0.0369, R_w = 0.0325. In all molecules, the immediate environment about tellurium is that of the saw-horse structure in which the lone pair is assumed to be stereochemically active and occupying an equatorial position in a distorted trigonal bipyramid. In 2 and 5, the terminal oxygen atoms are oriented toward tellurium, whereas in 4, one O(i-Pr) group is oriented toward tellurium, as it is in 8. In the latter cases, the terminal oxygen atoms act as weak bridges to form a pseudo dimeric species in 4 and a pseudo polymer in 8. Supramolecular interactions in 2 and 5 lead to a sulfur-bridged dimer in the former and a chlorine-bridged polymer in the latter. Key words: structure, tellurium, dimethyl, diphenyl, monothiocarbonates.

  Dimethyltellurium diiodide decomposes readily at room temperature in acetone and similar solvents, especially if water or an inorganic salt be present. Products include a tellurium-oxygen polymer containing some iodine and methyl groups, along with CH3I and various inorganic species. This decomposition is discussed in relation to other organometallid reactions.

  observed for α-(CH 3 ) 2 TeX 2 (X=Cl, Br, I) and (CH 3 ) 2 TeI 4 at various temperatures. The two 81 Br NQR lines were observed above 110 K in α-(CH 3 ) 2 TeBr 2 . The characteristic temperature dependence of the 127 I NQR line in α-(CH 3 ) 2 TeI. can be explained by the 3c—4e bond of the linear ITeI group. The positive temperatures dependence of the lowest 127 I NQR line in (CH 3 ) 2 TeI 4 is discussed

  摘要 观察了α-(CH 3 ) 2 TeX 2 (X=Cl, Br, I) 和(CH 3 ) 2 TeI 4 在不同温度下的NQR谱。在 110 K 以上的 α-(CH 3 ) 2 TeBr 2 中观察到两条 81 Br NQR 谱线。α-(CH 3 ) 2 TeI 中 127 I NQR 线的特征温度依赖性。可以用线性 ITeI 基团的 3c-4e 键来解释。(CH 3 ) 2 TeI 4 中最低的 127 I NQR 谱线的正温度依赖性基于从 Townes-Dailey 处理计算的电子布居进行了讨论。
