Abstract: | The reaction of palladium(II) bromide or palladium(II) iodide with the respective gallium(III) halogenide in the presence of aromatic solvents leads to the formation of palladium(II) tetrabromo— and tetraiodogallate. The compounds are isostructural {monoclinic, C2/m, PdGaBr4]2: a = 1267(2), b = 808(1), c = 722(1) pm, β = 94.5(1)°; PdGaI4]2: a = 1363(1), b = 849.9(4), c = 756.6(7) pm, β = 95.38(3)°}. The structures contain mononuclear complexes PdGaX4]2, where X— = Br— ( 1 ), I— ( 2 ). The crystal structures of 1 and 2 were determined by single‐crystal X‐ray diffraction. Crystals of both compounds turned out to be similarly twinned. |
