Infrared Spectrum and Structure of Thorimine (HNThH2)

Laser‐ablated thorium atoms react with ammonia to form thorimine (NHThH2), the first actinide imine to be reported. This work underscores the high reactivity of thorium atoms, particularly for NH bond activation, reveals a new type of multiple bond to actinide atoms, and shows that this bond is st...

Description
Summary:Laser‐ablated thorium atoms react with ammonia to form thorimine (NHThH2), the first actinide imine to be reported. This work underscores the high reactivity of thorium atoms, particularly for NH bond activation, reveals a new type of multiple bond to actinide atoms, and shows that this bond is strong for thorium as a result of an important contribution from the f orbitals. Ammonia is spontaneously activated by thorium to form the first actinide imine species (NHThH2) to be reported. Conjugation of the nitrogen lone pair gives a unique structure that has partial triple‐bond character as a result of important contributions from Th 5f orbitals.
