Abstract
The structures of Li2SiO3 [Cmc21, a = 9.396(1), b = 5.396(1), c = 4.661(1) Å] and Li2GeO3 [Cmc21, a = 9.634(2), b = 5.481(2), c = 4.843(1) Å] have been refined to R values of 0.022 and 0.016 respectively. The distances within the tetrahedral chains were found to be: Si−O = 1.677(2), Ge−O = 1.811(3) Å for bridging oxygen and Si−O = 1.591(1), Ge−O = 1.711 (2) Å for non-bridging oxygen. The Li atoms are coordinated tetrahedrally.
