“…It is also shorter than the corresponding Te−Cl(1) bond of 2.424(1) Å in trichloro(ethane-1,2-diolato- O , O ‘)tellurate(IV) ( 2 ) . In trichloro(2-phenylthiophenyl)tellurium ( 4 , Figure ) the Te(1)−S(1) and Te(1)−Cl(1) distances are 2.972(1) and 2.324(1) Å, respectively . These values suggest that there is a correlation for the opposite bond lengths.…”

Tellurium tetrachloride and allylphenyl sulfide react to form (1-thia-2-tellura-1-phenyl-4-chloro)cyclopentane 2,2,2-trichloride. The crystal and molecular structure were determined by single-crystal X-ray techniques. The crystals belong to the monoclinic system, space group P2(1)/c (No. 14) with a = 6.020(3) Å, b = 11.46(1) Å, c = 20.156(2) Å, beta = 97.53(2) degrees, V = 1379(1) Å(3), and Z = 4. The structure was refined to the final R value of 0.036. The coordination around Te(IV) is distorted psi octahedral with three Cl atoms in the equatorial positions. The axial Te(1)-C(1) bond opposite to the lone pair of electrons at the Te(IV) atom completes the coordination polyhedron. The intramolecular Te-S distance is 2.903(3) Å. Symmetric and asymmetric deformation modes were established to describe the plasticity of the Cl-Te-Cl fragments extracted from the Cambridge Structural Database. The hypervalency of Te(IV) manifests itself as plasticity in the equatorial plane of the coordination sphere. The NBO calculations show that all of the equatorial Te-Cl bonds are highly polarized and the electrons reside mainly on the Cl atoms.

“…The Te--C1 bond distance of 2.132 (7) ,~ is longer than the value of 2.037 ,~ predicted using the Pauling (1960) radii for Te (1.37 ,~) and Csp 2 (0.667 ~,). The Te--Cll and Te--C12 axial lengths are 0.11 and 0.10A longer, respectively, than the sum of the normal covalent radii (2.36 A; Ziolo & Troup, 1983) and may be compared with the values found in related compounds (Chakravorty et al, 1985).…”

The replacement of metal nanocrystal (NC)-based nonvolatile memories (NVMs) with polycrystalline silicon floating-gate memories is very attractive, since they demonstrate superior capability of charge localization and a reduction in cell-to-cell interference. Varying the size (ranging from 15.1 to 55.2 nm) and density (from 5:6 Â 10 11 to 3:2 Â 10 10 cm À2 ) of the metal NC affects the entire memory properties such as the charging/ discharging process, retention characteristic, and charge storage capability. Here, we investigated the effects of the size and density of platinum (Pt) NCs on the aforementioned memory characteristics by fabricating Pt-NC-embedded metal oxide semiconductor (MOS) capacitors using a direct self-assemble method. The flatband voltage shift, a measure of charge storage capability for NC-based NVMs, increased from 5.75 to 13.05 V as the mean size of the NCs was varied from 15.1 to 55.2 nm, which was relatively higher than that of other NC-based NVMs. Our studies revealed that the flatband voltage shift depends on not only the size and density of the NCs, but also the tunneling probability of the electrons, which is closely related to the applied electric field at a tunneling oxide. The relationships among the flatband voltage shift, the size and density of the NCs, and the applied electric field, which are revealed in this study, can be generally applicable to other NVMs based on various metal and semiconducting NCs. #
