Crystal structure of CaSiF6·2H2O(mP 2) and reevaluation of the SiIV-F bond-valence parameter R0
{{output}}
The structure of a second polymorph of CaSiF6·2H2O [calcium hexafluorido-silicate dihydrate; space group P2/c (No. 13), Pearson symbol mP2] was elucidated by single-crystal X-ray diffraction. It arose as an unexpected product when soda-lime glass was attacked... ...
