Abstract
Compound Ca<sub>12</sub>Al<sub>2</sub>(SiF<sub>6</sub>)<sub>4</sub>(SO<sub >4</sub>)<sub>3</sub>F<sub>16</sub>.45H<sub>2</sub>O was studied. A reproducible preparative method was found and the compound was characterized by both chemical analysis and by Debye- Scherer X-ray method. It was found that the substance crystallizes with the highest probability in the cubic system. The space groups 0<sup>5</sup>-I43 or T<sup>3</sup><sub>d</sub>-I43m can be assumed from the absence of reflexes of (hk1) type for h+k=2n+1, and of (hk0) for h+k=2n+1 and of (h00), where h is an odd number.
