Abstract

Cs2ZrSi6O15 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are three inequivalent Cs1+ sites. In the first Cs1+ site, Cs1+ is bonded in a 1-coordinate geometry to eleven O2- atoms. There are a spread of Cs–O bond distances ranging from 3.00–3.60 Å.
