Abstract:	Single crystal structural studies disclose hexagonal symmetry, $a = 7.099 ± 0.003 A ?$ , $c = 5.687 ± 0.002 A ?$ . The structure has been refined in space groups P6₃mc and finally in P6₃/mmc. The ideal cell contents are Ca₆Si₂O₁₀; any fluorine present is postulated to substitute randomly for oxygen with concommitant Ca omission. The close structural relations between this phase and Ca₃SiO₅ are described.
