trans-Tetraiodidobis(tri-p-tolylphosphine oxide-κO)tin(IV)
The centrosymmetric title compound, [SnI(4)(C(21)H(21)OP)(2)], is a monomeric complex that displays a nearly octa-hedral coordination of tin(IV), with an Sn-O bond distance of 2.159 (2) Å and an average Sn-I bond distance of 2.79 (3) Å.
متن کاملNew studies on trans-anethole oxide and trans-asarone oxide.
The widespread use of naturally occurring alkenylbenzenes as flavoring and fragrance agents has led to a long-standing interest in their toxicity and carcinogenicity. Among them several allyl- and propenylbenzenes have been found to be mutagenic and carcinogenic. It has been shown that the carcinogenicity of several allylbenzenes can be related to the formation of electrophilic sulfuric acid es...

The centrosymmetric title compound, C(18)H(26)O(4), was prepared in high yield from 4-acetoxy-styrene via Ru-catalysed homo-olefin metathesis. Exclusive formation of the E-configurated isomer was observed. In the crystal, a strong C-H⋯π inter-molecular inter-action links the mol-ecules together.

In the title compound, [PdBr(2)(C(21)H(21)As)(2)], the Pd(II) ion, residing on a centre of symmetry, is coordinated by two As donor atoms [Pd-As = 2.4276 (2) Å] and two Br anions [Pd-Br = 2.4194 (2) Å] in a distorted square-planar geometry [Br-Pd-As = 87.786 (7)°]. A weak intra-molecular C-H⋯Br inter-action occurs. In the crystal structure, inter-molecular C-H⋯Br inter-actions are observed.
متن کاملP-31 / Schlott P-31: Nodule Formation on Indium-Oxide Tin-Oxide Sputtering Targets
Nodule formation on ITO sputtering targets was investigated by stop action in-situ video observation, 3D-SIMS, and EPMA. Major cause of nodule formation is particulates from the sputtering system, less important are particulate inclusions in the target material. A nodule growth mechanism and strategies to minimize nodule formation are proposed.
