Ganteför, Gerd PtZnH<sub>5</sub>–, A σ-Aromatic Cluster Bowen, Kit H. Zhang, Xinxing eng 2015-07-08T09:58:08Z 2015-07-08T09:58:08Z 2014 Liu, Gaoxiang Alexandrova, Anastassia N. We report a joint photoelectron spectroscopic and theoretical study of the PtZnH<sub>5</sub>– cluster anion. This cluster exhibited an unprecedented planar pentagonal coordination for Pt and an unusual stability and high intensity in the mass spectrum. Both are due to the σ-aromaticity found in the H<sub>5</sub>-cycle supported by the 5d orbitals on the Pt atom. σ-Aromaticity in all-H systems has been predicted in the past but never found in experimentally observed species. Besides fundamental importance, mixed transition-metal hydrides can be found as intermediates in catalytic processes, and thus, the unexpected stability facilitated by σ-aromaticity can be appreciated also in practical applications.
