摘要:Two new copper(I)-thioarsenates(III), CsCu2AsS3(1) and KCu4AsS4(2), have been synthesized solvothermally in the presence of copper powder. Compound I is built up of trigonal AsS3 pyramid, tetrahedral CuAsS3 and CuS3 moieties forming 4-membered, 5-membered and 6-membered rings. The fusion of these rings produces layered anions [Cu2AsS3](-), and cesium cations are located between metal-sulfide layers. The structure of 2 consists of infinite [Cu2S2](2-) chain and layered [Cu6As2S6] linked to form a three-dimensional anionic framework, [Cu4AsS4](-), and containing channels in which the potassium cations reside.
