Abstract
The interaction of the interesting polynitrogen cyclic base 1,4,7-trimethyl-1,4,7-triazacyclononane (TMTACN) with the σ-acceptor iodine and π-acceptors tetracyanoethylene (TCNE), 7,7,8,8-tetracyanoquinodimethane (TCNQ) and tetrachloro-p-benzoquinone (chloranil) have been studied spectrophotometrically and cyclic voltametrically in chloroform at 20 °C. Based on the obtained data, the formed charge-transfer complexes were formulated as [(TMTACN)I]+·I3−, [(TMTACN)(TCNE)5], [(TMTACN)(TCNQ)3] and [(TMTACN)(chloranil)3] where the stoichiometry of the reactions, donor:acceptor molar ratios, were shown to equal 1:2 for iodine complex, 1:3 for chloranil and TCNQ complexes and 1:5 for TCNE complex.
