Dibromobis(4-methoxyphenyl)tellurium(IV) / Farran José, Joan (Universitat Autònoma de Barcelona. Departament de Geologia) ; Alvarez-Larena, Angel (Universitat Autònoma de Barcelona. Departament de Geologia) ; Piniella, J. Francesc (Joan Francesc) (Universitat Autònoma de Barcelona. Departament de Geologia) ; Germain, Gabriel (Université de Louvain. Unité de Chimie-Physique et de Cristallographie) ; Torres-Castellanos, Libardo (Universidad Nacional de Colombia. Departamento de Química)
The structur analysis shows that the title compound, [TeBr2(C7H7O)2], is isostructural with the corresponding dichloro compound. There are two molecules in the asymmetric unit in which the Te atom has pseudotrigonal bipyramidal coordination geometry. [...]

Bis(p-methoxyphenyl) Telluride / Farran José, Joan (Universitat Autònoma de Barcelona. Departament de Geologia) ; Alvarez-Larena, Angel (Universitat Autònoma de Barcelona. Departament de Geologia) ; Piniella, J. Francesc (Joan Francesc) (Universitat Autònoma de Barcelona. Departament de Geologia) ; Capparelli, Mario V. (Universitat Autònoma de Barcelona. Departament de Geologia) ; Torres-Castellanos, Libardo (Universidad Nacional de Colombia. Departamento de Química)
The title compound, C14H14O2Te, displays an angular geometry at tellurium, with a C-Te-C angle of 99. 5(1)º and Te-C distances of 2. 110(3) and 2. 112(3)A. The Te atom is displaced by 0. 1963(3) and 0. [...]
