Despite its chemical simplicity, a definitive description of the structure of TeO2 glass has remained elusive due to the complexity of the Te-O coordination environment. Here, in this work we probe the Te-O coordination environment in glassy TeO2 using 2D 125Te isotropic-anisotropic chemical shift correlation nuclear magnetic resonance (NMR) spectroscopy. The NMR results are consistent with the presence of two Te-O environments in this glass, characterized by their distinct set of 125Te chemical shift parameters. The dominant environment (~89%) is a distorted trigonal bipyramidal TeO4 unit, reminiscent of that observed in crystalline γ-TeO2. A second, minor (~11%) component can be assigned, on the basis of its chemical shift parameters, to a TeO3 unit. Lastly, the resulting average coordination number, nTeO, measured by 125Te NMR (nTeO ≈ 3.9) is higher than its previously reported value obtained using neutron diffraction (nTeO ≈ 3.7).
