Crystal structure of dicalcium chromate hydrate
Published online by Cambridge University Press: 06 March 2012
Abstract
Direct methods and Rietveld analysis were applied to high-resolution synchrotron X-ray powder diffraction data to solve the crystal structure of dicalcium chromate hydrate (Ca2CrO5⋅3H2O). The compound crystallizes in monoclinic symmetry (space group Cm, Z=2), with a=8.23575(5) Å, b=7.90302(4) Å, c=5.20331(3) Å, and β=98.0137(3)°. The structure is built from double-layers of CrO4 tetrahedra and CaO8 polyhedra that run parallel to the (001) plane.
