3-(Diphenylchalcogenophosphoryl)propionic acids as precursors for metal selenides and tellurides
Autor: Josef Novosad, Zdeněk Trávníček, Michal Babiak, Václav Kubát
Publikováno v: Polyhedron. 124:62-67
New reaction systems leading to cadmium, mercury and lead selenides and tellurides are reported. The chalcogenides were prepared by a simple, direct reaction between chalcogen, metal oxide or carbonate, and 3-(diphenylphosphino)propionic acid. The sy

A new synthetic route for the preparation of metal tellurides
Autor: Zdeněk Losos, Zdeněk Trávníček, Josef Novosad, Václav Kubát
Publikováno v: Inorganic Chemistry Communications. 38:8-10
A new method of synthesis for the formation of metal tellurides of the type MTe (M=Cd, Hg) is reported. The compounds were prepared by the reaction of cadmium carbonate (or mercury oxide, respectively) with tellurium and bis(diphenylphosphino)amine i

TeTe interactions in inorganic rings with sulfur donors
Autor: Josef Novosad, Maria José Calhorda, Luis F. Veiros, Nuno A. G. Bandeira
Publikováno v: Inorganica Chimica Acta. 356:319-327
Te(II) forms binuclear complexes with bridging [{S=P(Ph)(2)}(2)N](-) ligands and axial aryl groups with very long (TeTe)-Te-... distances, while Te(I) analogues with [S2P(R)(2)](-) have no axial ligands and exhibit a Te-Te bond. No such selenium comp
