主　　题：crystal structure solid state synthesis ternary alkali metal chalcogenide halide 

摘      要：A new ternary alkali metal chalcogenide halide, K3SI, has been synthesized by solid state reaction method and structurally characterized by X-ray crystallography. The crystal belongs to hexagonal, space group P63cm with a = 11.699（I ）, c = 5.8279（9） A°, Mr = 276.26, V = 690.8（1 ）A°^ 3, Z = 6, D, = 3.985 g/cm^3, F（000） = 756, μ = 9.913 mm^-1, S = 1.004, R = 0.0719 and wR = 0.2204. The title compound is the first example containing S anion in the ternary alkali metal chalcogenide halides family M3QX （M = alkali metal, Q = chalcogenide, X - halide）, which crystallizes in the hexagonal anti-perovskite structure type.
