How does one unravel peroxo complexation of most post‐transition elements in aqueous solutions at high pH? Two tellurium μ‐η 1 :η 1 ‐O 2 2− coordination peroxo compounds (NH 4 ) 4 Te 2 (μ‐OO) 2 (μ‐O)O 4 (OH) 2 and (NH 4 ) 5 Te 2 (μ‐OO) 2 (μ‐O)O 5 (OH)⋅1.28 H 2 O⋅0.72 H 2 O 2 were obtained from basic aqueous hydrogen peroxide solutions and characterized by single‐crystal X‐ray diffraction. Furthermore, 125 Te NMR investigations show that the crystal structures reflect the solution chemistry of the peroxotellurates. Gas‐phase DFT calculations corroborate the higher stability of peroxo over oxotellurate. More information can be found in the Full Paper by O. Lev, P. V. Prikhodchenko, et al. on page 2980 ff.
