摘要：
Three novel copper compounds, Rb4Cu4OCl10 (I), Rb[Cu3O](SeO3)(2)Cl (II), and RbCu3(OH)(SeO3)Cl-4(H2O)(3) (III) were prepared by chemical vapor transport (CVT) reactions method from mixtures of CuO, SeO2, RbCl, and CuCl2. The crystal structures of the three compounds were determined by direct methods. Compound I is a Rb analogue of ponomarevite, K4Cu4OCl10. Its crystal structure contains {[OCu4]Cl-10}(4-) clusters with oxocentered [OCu4](6+) tetrahedra as cores. The clusters are linked by the Rb+ cations. The crystal structure of II contains complex {[O2Cu6](SeO3)(4)Cl-2}(2-) layers formed by dimers of edge-sharing [OCu4](6+) tetrahedra interlinked via selenite groups and Cl- anions. The crystal structure of III is based upon {[(OH)Cu-3](SeO3)}(3+) layers formed by the [(OH)Cu-3](5+) tetrahedra attached to (SeO3)(2-) groups. The layers are linked via Cl- anions and via hydrogen bonds to H2O molecules.
