两个新的羟基硫酸盐骨架：有机硫原位合成和晶体结构

以甲基巯基四氮唑和巯基嘧啶为硫源, 用溶剂热合成法原位合成两个纯无机羟基硫酸盐骨架： Cu₃(SO₄)(OH)₄]_n(1)和K₂Co₃(OH)₂(SO₄)₃(H₂O)₂]_n (2). 在化合物1中, 一维带状折叠—Cu₃(OH)₄—阳离子链被硫酸根连接形成三维羟基硫酸铜骨架; 在化合物2中, 一维折叠Co₃(OH)₂阳离子链被硫酸根连接形成二维羟基硫酸钴阴离子骨架, 该阴离子骨架进一步被K⁺连接形成三维双金属纯无机骨架, 在该三维结构中存在K⁺传输通道. 实验结果表明, 有机硫作为硫源为合成羟基硫酸盐提供了一种新策略.

Two New Hydroxyl Sulfate Frameworks: In situ Synthesis of Organic Sulfur and Crystal Structures

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.
