Salts of sterically hindered chalcogen-varied Herz cations with various anions were synthesized. 4,6-Di-tert-butyl-substituted 1,2,3-benzothiaselenazolium (2), 2,1,3-benzothiaselenazolium (3), and 1,2,3-benzodiselenazolium (4) were obtained from corresponding 1,2,3-benzodithiazolium (1) or 2-bromo-4,6-di-tert-butylaniline (9) and were isolated as salts with [Cl] or/and [SbCl6] anions. Reaction of in situ prepared N,N,Te-tris(trimethylsilyl)-2-amino-3,5-di-tert-butyltellurophenole with SeCl4, S2Cl2, and SOCl2 resulted in elimination of Te and the formation of [4]2[TeCl6], [1]2[Te3Cl14], and [1]2[Te4Cl18] together with N-sulfinyl-2-amino-3,5-di-tert-butylphenyltellurium trichloride (11); expected 2,1,3-benzothiatellurazolium (5) and 2,1,3-benzoselenatellurazolium (6) were not observed. Compounds [1][Cl] (solvate with CHCl3), [2][SbCl6], [3][SbCl6], [4][SbCl6], [4]2[TeCl6], [1]2[Te3Cl14], [1]2[Te4Cl18], and 11 were structurally defined by X-ray diffraction. All of the [SbCl6] salts were isomorphous, and the [Te3Cl14]2– and [Te4Cl18]2– anions were previously unknown. Compound 11 has a significantly shortened intramolecular Te···O contact.
