Abstract: Using methylmercaptotetrazole and mercaptopyrimidine as sulfur sources,  two pure inorganic hydroxysulfate frameworks were obtained through in situ reaction under the solvo-thermal conditions： [Cu₃(SO₄)(OH)₄]_n(1) and [K₂Co₃(OH)₂(SO₄)₃(H₂O)₂]_n (2). In compound 1,  the puckered cationic —Cu₃(OH)₄— chain with one-dimensional ribbon was connected by sulfate to form a three-dimensional copper hydroxysulfate framework.  In compound 2,  the one-dimensional puckered cationic Co₃(OH)₂ chain was joined by sulfate to form a two-dimensional anionic cobalt hydroxysulfate layer,  which was further connected by K⁺ to form a three-dimensional pure inorganic framework with bimetallic centers. There was  K⁺ transport channels in the 3D structure. The experimental results show that organic sulfur as sulfur sources provides a new strategy for the synthesis of hydroxyl sulfate.
