“…Formal substitution of one of the dithiocarbamates in [Te(S 2 CNR 2 ) 4 ] by a uninegative ligand gives seven coordinate Te(IV) complexes of general formulas [TeR(S 2 CNR 2 ) 3 ] and [TeX(S 2 CNR 2 ) 3 ] (R ¼ aryl; X ¼ halide or pseudohalide) (293,304,309,312,319,323,(333)(334)(335)(336)(337)(338)(339)(340)(341)(342). In all cases the geometry at Te is distorted pentagonal bipyramidal, with the uninegative ligand (R or X) axial and one dithiocarbamate ligand spanning axial and equatorial positions.…”
