The optic modes of the hydrogen in the metal cluster compound Li6[Zr6Cl18H] are observed at 480 and 790 cm-1 using incoherent inelastic neutron scattering spectroscopy at ∼15 K, and confirmed using the spectrum of the deuterium substituted compound. This observation is rationalized in terms of a model with the hydrogen occupying a μ3-bridging position within the octahedral interstitial site with a Zr-H bond distance of ca. 2.0 Å. The terminal and bridge bonded chlorine vibrations are observed at frequencies of ∼280 and ∼190 cm-1, respectively.
