Preparation and crystal structures of tritellurium trisulfur bis(hexafluoroarsenate), ditellurium tetraselenium bis(hexafluoroantimonate), and ditellurium tetraselenium bis(hexafluoroarsenate)

125Te Mössbauer spectra of the polyatomic cations of tellurium

“…2ii. A crvstal structure of TeA2+ has not been revironments. A similar situation has been found to hold for Te64+ (12).…”

“…The solutions were transferred to Teflon holders with ported-but Te,Se4,+ and -T~, S ,~+ have been O-ring seals and frozen and stored in liquid nitrogen until demonstrated (12) to have a six-membered boatsuch time as the Mossbauer spectra were run. The sample referred to as Te4(SbzF1,), was prepared by reacting shaped ring structure with a Te-Te crOss-ring 20 mg of 70% enriched, dry '25Te with an excess of SbF, bond, similar to that of Fig.…”

Hexatellurium octaselenium hexakis(hexafluoroarsenate) sulfur dioxide

“…Preliminary precession photographs were used to check crystal quality. Further work on a Syntex P21 diffractometer using graphite-monochromatized Mo Ka radiation gave the experimental details summarized in Table 1 (Boldrini, Brown, Gillespie, Ireland, Luk, Slim & Vekris, 1976;Boldrini, Brown, Collins, Gillespie, Maharajh, Slim & Sawyer, 1985;Gillespie, Luk, Maharajh & Slim, 1977;Collins, Gillespie & Sawyer, 1987) no mixed cations were obtained in the present study. Instead, the composition of the crystals was established as (Tet)(Ses)(AsFt)6(SO2).…”

[Sb10Se10]2+, a Heteronuclear Polycyclic Polycation from a Room‐Temperature Ionic Liquid

“…[16] They have also become promising media for polymer science and nanotechnology. [12,17] Up to now, a number of mixed antimony/selenium polyanions, such as [ , [18] a few ternary compounds, for example, [Se 9 Cl]- 6 ] 2 , and the binary compound Sb 2 Se 3 are known. [19] Excellent optoelectronic performance makes Sb 2 Se 3 , which is a direct semiconductor with narrow band-A C H T U N G T R E N N U N G gap, interesting for application in solar-cell absorber films.…”

“…For the square E 4 2 + polycations, a number of mixed group 16 2 + polycyclic species were reported. [6] Very few cyclic or polycyclic polycations that contain elements of groups 15 and 16 are known. The first examples of mixed arsenic/chalcogen polycations, [As 3 S 4 ]…”
