摘要

Two modifications of Cs-2PdCl4 have been characterized by X-ray powder and single crystal diffraction, respectively. The crystal structures are described and the group-subgroup-relations between these structures are discussed. In addition to the tetragonal (P4/mmm (No. 123), a 7.4158(8) Angstrom, c = 4.6792(6) Angstrom) and the orthorhombic (Cmcm (No. 63), a = 10.529(1) Angstrom, b = 10.310(1) Angstrom, c = 9.460(1) Angstrom) modification DSC investigations and high-temperature X-ray diffraction experiments with synchrotron radiation show the existence of another modification or of yet unknown decomposition products. The phase transformation from the orthorhombic to the tetragonal polymorph is completely finished at 100degreesC. The second effect is detected at 319degreesC. References: 39
