【 摘 要 】

The ternary chloride Na₃MoCl₆ is obtained as red crystals from a disproportionation reaction of molybdenum dichloride, {Mo₆}Cl₁₂, in an acidic NaCl/AlCl₃ melt at 350 °C. The crystal structure (trigonal, P-31c, a = 687.1(1), c = 1225.3(2) pm, Z = 2, V = 501,0(1) 10⁶ pm³) is that of Na₃CrCl₆: within a hexagonal closest-packing of chloride ions two thirds of the octahedral voids are filled between the AB double layers with Na⁺/Mo³⁺, and between the BA layers with Na⁺.
