Abstract: | Tl4Pd3Cl10 – A Compound with a New [(PdCl2Cl2/2)4]4– Group Single crystals of Tl4Pd3Cl10 can be obtained by hydrothermal synthesis. They show tetragonal symmetry with lattice parameters a = 15.956(1) Å and c = 14.146(1) Å, Z = 8 and space group I42d (No. 122). The atomic arrangement of Tl4Pd3Cl10 is explored by X‐ray crystal structure analysis. Tl4Pd3Cl10 is the first example of a new structural type with a hitherto not isolated tetramer [(PdCl2Cl2/2)4]4– group. |
