Bis(dimethylamino)ethanediylidene]bis(dimethylammonium) bis(trifluoromethylchalcogenates(0)), (TDAE)[ECF 3 ] 2 (E ϭ Se, Te), are quantitatively formed from the reductions of E 2 (CF 3 ) 2 with tetrakis(dimethylamino)ethene, TDAE. Both compounds are bright yellow to orange solids which crystallize isostructurally with the corresponding sulfur derivative in the orthorhombic space group Pbca (No. 61).

[Bis(dimethylamino)ethandiyliden]bis(dimethylammonium)bis(trifluormethylchalcogenate(0)), (TDAE)[ECF 3 ] 2 (E ϭ Se, Te), werden quantitativ durch Reduktion von E 2 (CF 3 ) 2 mit Tetrakis(dimethylamino)ethen, TDAE, gebildet. Beide Verbindungen sind leuchtend gelbe bzw. orange Materialien, die isostruk-1039 (TDAE)[SeCF 3 ] 2 has alternatively been prepared by cation exchange from [NMe 4 ]SeCF 3 and (TDAE)Br 2 . turell mit dem entsprechenden Schwefelderivat in der orthorhombischen Raumgruppe Pbca (Nr. 61) kristallisieren. (TDAE)[SeCF 3 ] 2 wurde alternativ durch Kationenaustausch aus [NMe 4 ]SeCF 3 und (TDAE)Br 2 synthetisiert.
also performed, allowing the assignment of symmetric and asymmetric vibrations. The observed coinciding wavenumbers supported the skeletal C 2 symmetry structure for the Te 2 R 2 compounds.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
