Uranium(IV) hydride is a chemical compound of uranium and hydrogen with the chemical formula , a metal hydride.
In 1997, Souter et al. reported the production of by reacting laser ablated uranium atoms with dihydrogen and capturing the product on solid argon. The assignment of the structure was made using infrared spectroscopic evidence supported by DFT calculations. Uranium(IV) hydride has a quasi-tetrahedral (C) structure and is formed by the successive insertion of uranium into two hydrogen molecules:
Further reaction with hydrogen only produces dihydrogen complexes: (1 ⤠n ⤠6).
