Abstract
A single-crystal X-ray diffraction study of synthetic pseuowollastonite (CaSiO3) shows that this crystal has monoclinic C2/c symmetry, with a = 6.8394(5), b = 11.8704(9), c = 19.6313(7) Å, P = 90.667(6)°, and V= 1593.7(2) Å3. Basic features of the C2/c structure are similar to those previously determined with a C1̄ symmetry but fewer sites exist for the monoclinic space group: five symmetrically nonequaivalent Ca sites, three Si sites, and nine O sites.
