【摘要】 AgSCN的分子和晶体结构通过-射线分析修正,这个简单的无机盐晶中Ag的配位环境展现出一种稍微扭曲的揟斪中谓峁?在这个晶体中的每个银都与两个S原子和一个N原子相连,其中两个S原子和一个N原子分别来自三个不同硫氰酸根离子。在三维的AgSCN晶体空间结构中,每个配位体SCN-的上S原子都作为桥连接两个不对称的银原子,这个观察结果说明AgSCN晶体不仅仅只有一种文献报道的一位链状结构。更多还原

【Abstract】 An unexpected isomer of AgSCN has been determined by X-ray crystal structure analysis, which reveals that each silver(I) atom in the simple inorganic salt has a coordination environment of distorted T-shape fashion with two S and one N atoms coming from 3 different thiocyanate anions. Two Ag atoms are bridged asymmetrically by the S atom of SCN ligands, forming a 3 D structure of AgSCN. This clarifies the long-term parlance that ? D chain structure?is the only structure of AgSCN.更多还原
