The Crystal Structure of Tris(dimethyldithiocarbamato)-4-methoxyphenyltellurium(IV) Chloroform Solvate, [Te(Me2NCS2)3(MeOPh)].CHCl3.

Synthesis, Spectroscopic Studies, and Structural Studies of O,O-Alkylene Dithiophosphate and N,N-Dimethyl and Diethyl Dithiocarbamate Derivatives of Halodimethyltellurium(IV)

“…Several reports on organotellurium(IV) compounds with 1,1-dithio ligands have appeared on O -alkyl dithiocarbonates, − N , N -dialkyl dithiocarbamates, − and O , O -dialkyl and alkylene dithiophosphates, − ,− but reports on related halo derivatives of the type Me 2 TeXL have been limited to a few N , N -dialkyl dithiocarbamates, along with more recent reports of Me 2 TeX[S 2 COR] and Me 2 TeX[S 2 CN(CH) n CH 2 ]. , In attempts to prepare mixed ligand complexes including Me 2 Te[S 2 CNR 2 ][S 2 COR], and the halo derivatives were formed as intermediates; several of these have now been isolated. The synthesis and characterization are reported of O , O -alkylene dithiophosphate and dithiocarbamate derivatives of halodimethyltellurium(IV), where X = Cl, Br, I, G = −CMe 2 CMe 2 −, −CH 2 CMe 2 CH 2 −, and −CH 2 CEt 2 CH 2 −, and Me 2 TeX[S 2 CNR 2 ], where R = Me, Et.…”

Synthesis and Spectroscopic Characterization of Pyrrolidyl and Piperidyl Dithioformate Derivatives of Dimethyltellurium(IV) Compounds. Crystal Structures of Me2Te[S2CN(CH2)3CH2]2, Me2Te[S2CN(CH2)4CH2]2, Me2Te{[S2CN(CH2)3CH2][S2CN(CH2)4CH2]}, Me2TeCl[S2CN(CH<

“…The importance of supramolecular associations in molecular compounds of tellurium complexes with sulfur ligands has been recently reviewed . Several reports have appeared on organotellurium(IV) derivatives with 1,1-dithio ligands including O -alkyl dithiocarbonates − and N , N -dialkyl dithiocarbamates. − We recently reported on dimethyltellurium derivatives of monothio ligands including pyrrolidyl and piperidyl monothioformate derivatives, but unfortunately were only able to obtain structural information on ethyl derivatives. We now report on the synthesis and spectroscopic characterization of dimethyltellurium(IV) pyrrolidyl and piperidyl dithioformates, Me 2 Te[S 2 CN(CH 2 ) n CH 2 ] 2 and Me 2 TeX[S 2 CN(CH 2 ) n CH 2 ], where n = 3, 4 and X = Cl, Br, and I. X-ray crystal structures are reported for Me 2 Te[S 2 CN(CH 2 ) 3 CH 2 ] 2 (1) , Me 2 Te[S 2 CN(CH 2 ) 4 CH 2 ] 2 (2) , Me 2 Te{[S 2 CN(CH 2 ) 3 CH 2 ][S 2 CN(CH 2 ) 4 CH 2 ]} (3) , Me 2 TeCl[S 2 CN(CH 2 ) 3 CH 2 ] (4) , Me 2 TeBr[S 2 CN(CH 2 ) 3 CH 2 ] (5) , Me 2 TeI[S 2 CN(CH 2 ) 3 CH 2 ] (6) , Me 2 TeCl[S 2 CN(CH 2 ) 4 CH 2 ] (7) , and Me 2 TeI[S 2 CN(CH 2 ) 4 CH 2 ] (9) .…”
