nd(10) 金属氰化物具有有趣的配位化学，其中所涉及的金属和氰化物配体的性质相结合，形成具有有吸引力的物理性质的配位聚合物。 X射线光电子能谱（XPS）已被证明是提供过渡金属氰化物配位化学信息的合适技术，包括所涉及金属的配位几何结构、CN配体的配位模式以及由于过渡金属氰化物中众所周知的π背键合效应而导致的电子密度重新分布等。本文讨论了nd(10)金属氰化物、CuCN、AgCN、AuCN、Zn(CN)(2)、 Cd(CN)(2) 和 Hg(CN())2。 XPS 数据的结果与相应的拉曼光谱进行了补充。据我们所知，这是首次根据 XPS 数据对该金属氰化物系列进行系统研究，并考虑了该系列每个成员的可用结构信息。本文讨论的结果是相关的，因为这一系列金属氰化物具有重要的工业应用并具有相关的功能特性。在这六种 nd(10) 金属氰化物中，只有铜的 NIST XPS 数据库有可用信息。
nd(10) metal cyanides have an interesting coordination chemistry where the properties of the involved metal and the cyanide ligand are combined to form coordination polymers with attractive physical properties. X-ray photoelectron spectroscopy (XPS) has proven to be an appropriate technique to provide information on the coordination chemistry of transition metal cyanides, including coordination geometry for the involved metal, coordination mode of the CN ligand, and electron density redistribution due to the well-known pi-back bonding effect in transition metal cyanides, etc. This contribution discusses on the structural information contained in the XPS spectra of nd(10) metal cyanides, CuCN, AgCN, AuCN, Zn(CN)(2), Cd(CN)(2) and Hg(CN())2. The results from XPS data were complemented with the corresponding Raman spectra. To the best of our knowledge, this is the first systematic study of this metal cyanides series from XPS data and considering the available structural information for each of the series members. The results herein discussed are relevant because this series of metal cyanides finds important industrial applications and have relevant functional properties. Of these six nd(10) metal cyanides, only for copper the NIST XPS Data Base has available information.
