Atomically precise Pd-thiolate clusters are well-known for their well-defined structures and diverse applications involving catalysis, sensors, and biomedicine. While many of these clusters have been studied, their molecular structures typically feature a tiara-like arrangement. In this study, we present the first example of a non-tiara-like Pd-thiolate cluster: the octahedral Pd 6 (SC 6 H 11 ) 12 (denoted as Pd 6 -Oct). The composition and geometric structure of the cluster were characterized using electrospray ionization mass spectrometry (ESI-MS) together with single-crystal X-ray diffraction (SXRD). Despite having a similar chemical composition to tiaralike Pd 6 (SC 2 H 4 Ph) 12 (denoted as Pd 6 -Tia), Pd 6 -Oct exhibits a distinctly different geometric structure. Additionally, UV−vis−NIR absorption spectroscopy combined with quantum chemical calculations provided valuable insights into the electronic structures of these clusters. The excited-state dynamics, host−guest chemistry, and the catalytic properties of Pd 6 -Oct and Pd 6 -Tia were examined to compare their structure−property relationships. This research represents significant advances in the synthesis and understanding of structure−property correlations in Pd-thiolate clusters.
