两个新的羟基硫酸盐骨架:有机硫原位合成和晶体结构

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

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:[Cu_(3)(SO_(4))(OH)_(4)]_n(1)和[K_(2)Co_(3)(OH)_(2)(SO_(4))_(3)(H_(2)O)_(2)]_n(2).在化合物1中,一维带状折叠—Cu_(3)(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Co_(3)(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.

Using methylmercaptotetrazole and mercaptopyrimidine as sulfur sources,two pure inorganic hydroxysulfate frameworks were obtained through in situ reaction under the solvo-thermal conditions:[Cu_(3)(SO_(4))(OH)_(4)]n(1)and[K_(2) Co_(3)(OH)_(2)(SO_(4))3(H 2 O)2]n(2).In compound 1,the puckered cationic—Cu_(3)(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 Co_(3)(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.
