Electron spin resonance studies of silver cycloalkenyl radicals by γ-irradiation of polycrystalline silver cycloalkene complexes have been extended to include the effect of alkyl substitution at the double bond, the effect of conjugation in cyclic diolefins and the effect of anions, on the formation of these silver cycloalkenyl radicals.

Paramagnetic species have been detected in γ-irradiated polycrystalline silver perchlorate – cycloalkene complexes at room temperature and identified as Ag+ cycloalkenyl radicals, with spin density on Ag decreasing from 4.6 to 1.5% with increasing size of the cycloalkenyl ring. The extent of the spin density on Ag increases with the stability of the parent complexes.
