“…Annealing of the product in an evacuated quartz glass ampoule at 700 °C for 1 h afforded crystalline cubic ZnTe and traces of tellurium as evidenced by powder XRD (Figure b). These observations align with the previously reported thermolysis of [Zn(TeC 6 H 2 Me 3 ‐2,4,6) 2 (pyridine) 2 ] in paraffin oil at 270 °C and on adding complex 1 in trioctylphosphine into the hot dodecylamine at either 180 °C or 240 °C.…”

“…Correspondingly, the Te–Zn–Te angles in 1 [126.12(3)°], 2 [124.11(3)°], and 3 [124.126(15)°] are greatly expanded, whereas the Te–Zn–Br angle in complex 4 [114.30(11)° and 117.39(5)] is considerably smaller, probably a consequence of the decreased steric demands of Br relative to Te. The Zn–Te bond lengths of 1 [2.5795(8) and 2.5911(8) Å], 2 [2.6133(13) and 2.6001(13) Å], 3 [2.5773(2) Å] and 4 [2.478(2) and 2.5349(9) Å] agree very well with the Zn–Te distances in related complexes [Zn{TeSi(SiMe 3 ) 3 } 2 (py) 2 ] and [Zn(Te‐2,4,6‐(CH 3 ) 3 C 6 H 2 ) 2 (py) 2 ] , . The Zn–N bonds in 1 , 2 , 3 and 4 range from 2.095(5) to 2.165(2) Å in good agreement with reported values …”

“…The silyltellurolato complex of zinc, zinc[bis(tris(trimethylsilyl)silyltellurolate)], possesses sufficient thermal stability and volatility for the vapor‐phase deposition of thin zinc telluride films . The 2,4,6‐trimethylphenyltellurolato complexes of zinc, and their Lewis base adducts, have been reported to decompose in the solid state to give polycrystalline zinc telluride . The complex zinc(tmeda)bis(phenyltellurolato) (where tmeda denotes N,N,N ′, N ′‐tetramethylethylenediamine) has been especially fruitful in the fabrication of ZnTe films, nanoparticles and nanowires , .…”

Anaerobic treatment of Zn(tmeda)Br2, where tmeda denotes N,N,N′,N′‐tetramethylethylenediamine, with a solution of Na(TeAr), sodium aryltellurolate, in ethanol in a 1:2 stoichiometry led to the formation of highly air sensitive Zn(tmeda)(TeAr)2 (1–3), while a 1:1 stoichiometry afforded Zn(tmeda)Br(TeAr) (4). Crystallography revealed all complexes to be monomeric with four coordinate central zinc atoms bound to tmeda and two TeAr, or a TeAr and a Br ligand. Upon mixing two symmetrically substituted Zn(tmeda)(TeAr)2 complexes in solution, 125Te NMR revealed a facile ligand exchange providing Zn(tmeda)(TeAr)(TeAr′). In addition, Zn(tmeda)(TeAr)(TeAr′) complexes form on mixing symmetric Zn(tmeda)(TeAr)2 complexes and (TeAr′)2. The lability of the zinc complexes was put to advantage in ligand‐substitution reactions wherein treatment of SnCl4 with Zn(tmeda)(TeAr)2 affords Sn(TeAr)4 in excellent yields without the concurrent formation of the redox product (TeAr)2. The apparent lability of the Zn–Te bond prevented the volatilization of 1–3 for their use as chemical vapor deposition precursors for the fabrication of ZnTe thin films. On heating, to volatize the complexes, the complexes decompose to cubic ZnTe and TeAr2 sublimes from the samples. Thermal gravimetric analysis indicates the loss of tmeda followed by the loss of TeAr2.

“…Even though metal chalcogenolato complexes have been widely studied previously as single-source precursors to group 12 chalcogenide semiconductor materials, 6,12,18 the development of zinc tellurolate molecular chemistry is still limited. [19][20][21] A pyridine adduct of a mesityltellurolate zinc complex prepared by Bochmann et al 22 and the dimeric compound [Zn{TeSi-(SiMe 3 ) 3 } 2 ] 2 prepared by Bonasia and Arnold 23 have been known to generate ZnTe upon pyrolysis. In our study, we synthesized a polymeric phenyltellurolate zinc complex using a dealkylsilation process that was similarly employed to obtain a organotellurolato cadmium compound.…”
