Determination of the crystal structure of Pb2CrO5

The crystal structure analysis of Pb2CrO5 is determined by comparison with powder x-ray and electron diffraction data. The structure is monoclinic: c2/m. All of the atom positions are determined by considering the calculated values of d spacings, line intensities, bond lengths, and bond angles. A new set of lattice parameters are a=14.018, b=5.683, c=7.143 Å, and β=115.23 °. A preliminary result on photoconductivity in a Pb2CrO5 ceramic disk is also given.
