In 1997, Souter et al. reported the production of UH4 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.[1] Uranium(IV) hydride has a quasi-tetrahedral (Cs) structure. UH4 is formed by the successive insertion of uranium into two hydrogen molecules:
Further reaction with hydrogen, only produces dihydrogen complexes: UH4(H2)n (1 ≤ n ≤ 6).[2]
