ROOM TEMPERATURE SYNTHESIS OF THALLIUM CHALCOGENIDES IN AMMONIA AND n-BUTYLAMINE

4 Aluminium, gallium, indium and thallium

“…157 Direct combination of the elements at room temperature in liquid ammonia or n-butylamine gave Tl[TlS 2 ], Tl[TlSe 2 ], Tl 2 Se, Tl 5 Se 3 , Tl 5 Te 3 and (TlAgTe). 158 It was recognised long ago that Tl() alkoxides are tetrameric with a cubane-like structure. Recent single-crystal X-ray diffraction measurements showed that various bulky alkoxide ligands in [TlOR] 4 (R = CHMe 2 , CMe 3 and CH 2 CMe 3 ), also had a cubane structure, whereas others such as 2,6-dimethyl-and 2,6-diisopropylaryloxides, where the ligands are even larger and steric effects are more important, formed polymeric chains.…”
