Whereas the self-assembly of pentaphosphaferrocenes [CpFe(η-P)] (Cp = Cp*, Cp, and Cp) with Cu and Ag salts has been well-studied in the past, the coordination chemistry toward Au complexes has been left untouched so far. Herein, the results of the self-assembly processes of [CpFe(η-P)] with Au salts of different anions (GaCl, SbF, and Al(OC(CF)) (TEF)) are reported. Next to a variety of molecular coordination products, the first coordination polymers based on polyphosphorus ligand complexes and Au salts are also obtained. Thereby, a 2D coordination polymer comprising metal vacancies is isolated. In all products, the Au centers are coordinated in a linear or a trigonal planar environment. In solution, highly dynamic processes are observed. Variable-temperature NMR spectroscopy, solid-state NMR spectroscopy, and X-ray powder diffraction were applied to gain further insight into selected coordination compounds.
尽管过去对五磷代二茂铁[CpFe(η-P)]（Cp = Cp*、Cp和Cp）与铜盐和银盐的自组装已进行了充分研究，但迄今为止，其与金配合物的配位化学仍未涉及。本文报道了[CpFe(η-P)]与不同阴离子的金盐（GaCl、SbF和Al(OC(CF))（TEF））自组装过程的结果。除了各种分子配位产物外，还获得了基于多磷配体配合物和金盐的首个配位聚合物。由此，分离出一种包含金属空位的二维配位聚合物。在所有产物中，金中心在直线型或三角平面环境中配位。在溶液中，观察到高度动态的过程。应用变温核磁共振光谱、固态核磁共振光谱和X射线粉末衍射来进一步深入了解选定的配位化合物。
