Abstract
Samples of dilead(II) pentaoxochromate(VI) Pb2CrO5, have been synthesised by direct fusion of PbO and PbCrO4, and the composition characterised by gravimetric and neutron activation analysis. X-Ray powder diffraction measurements of d-spacings and line intensities revealed that the structure is monoclinic and isomorphous with lead pentaoxo-sulphate and -selenate. A computer method was employed to aid in fixing the position of the lead and chromium atoms in the unit cell and indexing the high angle Bragg reflections. The lattice parameters were found to be a= 14·01, b= 5·68, c= 7·15 Å, β= 115·1°.Keywords
