Abstract

Palladium tetrammine dichromate, [Pd(NH3)4]Cr2O7, was obtained by precipitation from [Pd(NH3)4]Cl2·H2O and (NH4)2Cr2O7. The X-ray diffraction pattern of this compound corresponds to a new phase, which was indexed in the triclinic system, but on a cell that should be considered as preliminary. From the chemical analysis and the X-ray absorption experiments at both K-edges of Pd and Cr, we conclude that the surrounding of these atoms is kept during formation.
