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(1), c = 5.8279(9) (A), Mr = 276.26, V = 690.8(1)(A)3, Z = 6, Dc = 3.985 g/cm3, 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.
