High-field Sn-119 Mossbauer spectroscopy was performed on a range of tin-containing ternary and binary silicate glass systems. All the glasses unambiguously exhibited a positive value for e(2)qQ for the Sn2+ valence state. Determination of the sign of e(2)qQ indicates that the electron distribution around each Sn nucleus is similar at all the tin atoms, which is a significant finding for glasses. These results suggest that the electronic state of the Sn2+ is dictated by its non-bonding electron orbital, which has strong p(z) character, and which provides the dominant contribution to the electric field gradient present at the Sn-119 nucleus.
