In an effort to search for novel quaternary bismuth sulfide compounds, we have explored K/Ag/Bi/S system and encountered novel quaternary bismuth sulfide compound, KAgBi<sub>2</sub>S<sub>4</sub> using K<sub>2</sub>S<sub>x</sub> molten salt at intermediate temperature. The black hexagonal crystals of KAgBi<sub>2</sub>S<sub>4</sub> are obtained at 350℃ and crystallized in the space group P6<sub>3</sub>/mmc (no.194) with a=4.0216(3)Å, c=30.066(3)Å, γ=120°, Final R<sub>1</sub>/wR<sub>2</sub>=4.37/13.15%. The structure of KAgBi<sub>2</sub>S<sub>4</sub> is composed of negatively charged [M<sub>3</sub>S<sub>4</sub>]<sub>n</sub> <sup>n-</sup> layers separated by charge balancing K<sup>+</sup> ions which are loosely packed in the interlayer spaces.
