Abstract
Crystal structure of α-CaSi2O5 synthesized at conditions of 1500°C and 10 GPa, has been solved and refined in œntrosymmetric space group PL The structure is closely related to that of titanite, CaTiSiO5 and consists the square pyramid five-fold coordination of silicon by oxygen. The ionic radius for five-coordinated Si calculated from the bond distances is 0.33 Å.
