Abstract
The structure of Ca2As2O7 (a 0=7.05,b 0=9.30,c 0=4.89 Å; β=101.3°; space groupC2/m-C 32h ;Z=2) has been solved from 465 independent X-ray intensities collected on aWeissenberg-type diffractometer up to anR-factor of 2.4% for all intensities. The structure of Ca2As2O7 represents a further Thortveitite structure type.
