摘要：

The structure of fresnoite, Ba2(TiO)Si2O7, was determined from the Patterson projection P(uv) and refined by the least-squares method using three-dimensional single-crystal data. Its unique feature is the tetragonal-pyramidal coordination of titanium. Sheets made up of heterocyclic five-membered rings of Ti-0 tetragonal pyramids and Si-0 tetrahedra are held together by Ba-O bonds. The bonds within the sheet are predominantly covalent, and the inter-sheet bonds are mainly ionic in character. © 1969, Walter de Gruyter. All rights reserved.
