Novel charge-transfer complexes have been prepared from organic stable radicals such as 4-dialkylamino-TEMPO or verdazyl radical and electron acceptors. Among them, the CT complexes from 4-dimethylamino- or 4-azetidino-TEMPO and DDQ formed salt-like complexes of protonated 4-dialkylamino-TEMPO, and the substituted 1,4-benzoquinone-hydroxylate upon recrystallization from a moist acetone. A series of ternary complexes consisting of organic stable radicals with their corresponding cation salts have been prepared by ball-milling of the solids. The magnetic behavior of the ternary complexes is discussed.
