Recent theoretical calculations have shown that Ir should behave as a chemical analogue to N, with the result that IrUO + , like known NUO + , is predicted to be a stable species isoelectronic with UO 2 2+ , the uranyl dication. The target heterometallic analogue to uranyl has now been prepared by direct laser desorption/ionization of a U/Ir alloy, and by oxidation of UIr + with N 2 O and C 2 H 4 O. Properties of UIr + , UPt + , and UAu + bimetallic ions have been studied. They demonstrate direct actinide–transition metal bonding, and support the concept of “autogenic isolobality”.
