Abstract

The platinum hydride cluster Pt₁₂H₂₄ ^- is studied in gas phase by a combination of trapped ion electron diffraction and density functional theory computations. We find a cuboctahedral platinum cage with bridge bound hydrogen atoms. This unusual structure is stabilized by Pt-H-Pt multicenter bonds and shows characteristics of spherical aromaticity.

Keywords: cluster compounds; density functional theory; electron diffraction; hydrides; platinum.
