To extend organoactinide chemistry beyond uranium, reported here is the first structurally characterized transuranic hydrocarbyl complex, Np[ η 4 ‐Me 2 NC(H)C 6 H 5 ] 3 ( 1 ), from reaction of NpCl 4 (DME) 2 with four equivalents of K[Me 2 NC(H)C 6 H 5 ]. Unlike the U III species, the neptunium analogue can be used to access other Np III complexes. The reaction of 1 with three equivalents of HE 2 C(2,6‐Mes 2 ‐C 6 H 3 ) (E=O, S) yields [(2,6‐Mes 2 ‐C 6 H 3 )CE 2 ] 3 Np(THF) 2 , maintaining the trivalent oxidation state.
