Observation of bridging and terminal metal hydrides by solid-state deuterium NMR spectroscopy: application to bis(cyclopentadienyl)zirconium dideuteride
Journal Article

· Inorg. Chem.; (United States)
The solid-state deuterium NMR spectrum of ((eta/sup 5/-C/sub 5/H/sub 5/)/sub 2/Zr/sup 2/H/sub 2/)/sub x/ has been measured at 46 and 61 MHz. Two deuterium sites were detected: a Zr-/sup 2/H terminal bond and a Zr-/sup 2/H-Zr bridging bond. The values found for the deuterium quadrupole coupling constant for the terminal and bridging sites are 46.7 (5) and 32.7 (20) kHz, respectively. A discussion is presented regarding assignment of deuterium quadrupole coupling constants to terminal or bridging metal hydride sites.
