Abstract: | ![]() Two New Iodopalladates with Identical Chemical Formula: Rb2PdI4 · I2 – a New Structure Type with Insertion of I2 Molecules – and Rb2PdI6 Rb2PdI4 · I2 is the first rubidium iodopalladate(II) which could be prepared. Despite showing the same formula type, the compound is not isotypic to Cs2PdI4 · I2. The crystal structure of Rb2PdI4 · I2 was explored by X‐ray crystal structure analysis. Rb2PdI4 · I2 shows orthorhombic symmetry, space group Pnma (No. 62) with lattice parameters a = 7.982(1) Å, b = 12.267(1) Å, c = 14.599(1) Å, Z = 4. Palladium is coordinated by four iodine atoms building the typical square‐planar coordination. Further iodine is inserted as I2 molecules. Another compound with the same empirical formula but octahedrally coordinated PdIV – Rb2PdI6 – could be obtained microcrystallinic in connection with Rb2PdI4 · I2. |
