Abstract
Rb2PdI4. I-2 is the first rubidium iodopalladate(II) which could be prepare d. Despite showing the same formula type, the compound is not isotypic to C s2PdI4. I-2. The crystal structure of Rb2PdI4. I-2 was explored by X-ray cr ystal structure analysis. Rb2PdI4. I-2 shows orthorhombic symmetry, space g roup Pnma (No. 62) with lattice parameters a = 7.982(1) Angstrom, b = 12.26 7(1) Angstrom, c = 14.599(1) Angstrom, Z = 4. Palladium is coordinated by f our iodine atoms building the typical square-planar coordination. Further i odine is inserted as I-2 molecules. Another compound with the same empirica l formula but octahedrally coordinated Pd-IV - Rb2PdI6 - could be obtained microcrystallinic in connection with Rb2PdI4. I-2.
