I try to get data on the structure of beta-cristobalite, SiO2. On I find the following:
Cristobalite Downs R T, Palmer D C American Mineralogist 79 (1994) 9-14 The pressure behavior of alpha cristobalite P = room pressure _database_code_amcsd 0001629 4.9717 4.9717 6.9223 90 90 90 P4_12_12 atom x y z B(1,1) B(2,2) B(3,3) B(1,2) B(1,3) B(2,3) Si .30028 .30028 0 .0077 .0077 .00401 -.0003 .0008 -.0008 O .2392 .1044 .1787 .0244 .0086 .0062 -.0013 .0027 .0005
I have no idea what this means. I know the unit cell should have 4 Si atoms, and each should bond to 4 O atoms. What information is given from these numbers (all of them)?
