摘要:Three copper-rich framework selenoarsenates, (H2en)1.5[Cu8(mu 8-Se)(AsSe4)6/2] (1), (H2dap)1.5[Cu8(mu 8-Se)(AsSe4)6/2] (2), and Na2(H2dap)0.5[Cu8(mu 8-Se)(AsSe4)6/2] (3), were synthesized under solvothermal conditions. These three compounds are isostructural and contain a 3D Cu-As-Se framework constructed from novel icosahedral Cu8Se13 clusters linked by As5+, with counterions located in the cavities. The icosahedral Cu8Se13 clusters represent the first icosahedral Cu-Se unit found in 3D framework chalcogenides, and contain an unusual mu 8-cubic bridging Se2 ion at the core site. The covalent 3D Cu-As-Se framework is rigid and not sensitive to the shape and charge density of counterions.
