  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.

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.

  Mixed ligand derivatives of Me₂TeLL'₂, where L = N,N-dialkyl dithiocarbamate or O,O-alkylene dithiophosphate and L' = O-alkyl dithiocarbonate, have been synthesized and characterized by elemental analysis, ¹H, ¹³C, ³¹P, and ¹²⁵Te NMR spectroscopy and infrared and Raman spectroscopy, and X-ray crystallography. Me₂Te[S₂CNMe₂][S₂COEt], 8: P[Formula: see text] (no. 2), with cell parameters a = 10.073(3) Å, b = 10.139(2) Å, c = 9.108(2) Å, α = 92.36(2)°, β = 115.55(2)°, γ = 111.19(2)°, V = 760.7(4) ų, Z = 2, R = 0.0343, R_w = 0.0296. Me₂Te[S₂CNEt₂][S₂COMe], 9: P2₁/c (no. 14) with cell parameters a = 9.881(4) Å, b = 17.671(3) Å, c = 10.149(4) Å, β = 113.65(3)°, V = 1623.3(10) ų, Z = 4, R = 0.0567, R_w = 0.0514. The immediate environment about tellurium in both molecules is essentially that of a saw-horse structure in which the lone pair is apparently stereochemically active and occupying an equatorial position in a distorted trigonal bipyramid. The S-Te-S angles in the two molecules are 166.87(6)° and 162.0(1)° for 8 and 9, respectively. In both molecules, the Te—S bonds to the dithiocarbamate groups are slightly shorter than those to dithiocarbonates. The dithiocarbamate groups are oriented to give secondary interactions involving the apparently terminal sulfur atoms resulting in Te—S distances of 3.205(2) and 3.277(4) Å, respectively, in 8 and 9. However, only in 9 is there a similar Te—S distance of 3.346(5) Å involving the S₂COMe group because in 8, the OEt group of S₂COEt, rather than the terminal S atom, is oriented toward Te. Key words: structure, tellurium, methyl, dithiocarbamates, dithiocarbonates, dithiophosphates.

  Me₂TeLL'₂的混合配体衍生物已经通过元素分析、¹H、¹³C、³¹P和¹²⁵Te核磁共振光谱、红外和拉曼光谱以及X射线晶体学合成和表征，其中L = N,N-二烷基二硫代氨基甲酸盐或O,O-烷基二硫代磷酸酯，L' = O-烷基二硫代碳酸酯。Me₂Te[S₂CNMe₂][S₂COEt]，8：P[Formula: see text]（编号2），晶胞参数a = 10.073(3) Å，b = 10.139(2) Å，c = 9.108(2) Å，α = 92.36(2)°，β = 115.55(2)°，γ = 111.19(2)°，V = 760.7(4) ų，Z = 2，R = 0.0343，R_w = 0.0296。Me₂Te[S₂CNEt₂][S₂COMe]，9：P2₁/c（编号14），晶胞参数a = 9.881(4) Å，b = 17.671(3) Å，c = 10.149(4) Å，β = 113.65(3)°，V = 1623.3(10) ų，Z = 4，R = 0.0567，R_w = 0.0514。这两种分子中碲的周围环境基本上是一个锯齿结构，其中孤对电子显然是立体化学活性的，并占据一个畸变的三角双锥体的轴位。两种分子中的S-Te-S角分别为166.87(6)°和162.0(1)°。在这两种分子中，碲与二硫代氨基甲酸盐基团的键稍短于与二硫代碳酸酯的键。二硫代氨基甲酸盐基团的定向使得似乎末端硫原子参与次要相互作用，导致8和9中分别为3.205(2) Å和3.277(4) Å的Te-S距离。然而，仅在9中，涉及S₂COMe基团的Te-S距离为3.346(5) Å，因为在8中，S₂COEt的OE基团而不是末端S原子定向向碲。关键词：结构、碲、甲基、二硫代氨基甲酸盐、二硫代碳酸酯、二硫代磷酸酯。

  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
