Radii of Cu + , Ag + , Au + and Tl + cations are determined by the additive method from interatomic distances in molecular and/or crystalline halides, oxides, chalcogenides and cyanides with different coordinations of atoms, and then recalculated for the 6‐coordination number. The averaged (from 74 structures) values of revised radii are equal to r (Cu + ) = 0.74 Å, r (Ag + ) = 0.99 Å, r (Au + ) = 0.92 Å, r (Tl + ) = 1.22 Å, which are consistent with radii calculated from direct cation–cation contacts in ultimately compressed metals.
