摘要: Theoretical calculations utilizing relativistic ZORA Hamiltonian point to the conceivable existence of an IrNO3 molecule in C3v geometry. This minimum is shown correspond genuine nonavalent iridium nitride trioxide, which a neutral analogue cationic [IrO4 ]+ species detected recently. Despite presence anion, protected by substantial barriers exceeding 200 kJ mol-1 against transformations leading, for example, global (O=)2 Ir-NO, contains metal at lower formal oxidation state.
