摘要: By reacting cadmium salts with H2SO4 in the presence of organic amines or directly amine sulfates under hydrothermal conditions, it has been possible to prepare three linear linarite topology, compositions [H3N(CH2)2NH3]2[CdCl2(SO4)][SO4]·H2O, I, [HN(CH2)6NH][CdBr2(SO4)], II, [HN(CH2)6NH][CdCl2(SO4)], III. A layered sulfate composition [H3N(CH2)3NH3][Cd2(H2O)2(SO4)3], IV, also obtained. These are first examples a family organically templated metal interesting structural features. In chains, CdX4O2 (X = Cl, Br) octahedron shares two trans-edges form an [Mφ4] (φ = anionic ligand) chain decorated by SO4 tetrahedron that adopts staggered arrangement on either side chain. IV is constructed fusion four-membered ring ladders involving edge sharing between and octahedron. appears be member containing octahedral–tetrahedral 2D net wherein connected at all four corners.
