Abstract
Abstract Charge-transfer complexes between 1-methylpiperazine (1MPIPZ) as a donor with the π-acceptors 7,7,8,8-tetracyanoquinodimethane (TCNQ), tetracyanoethylene (TCNE), 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ), 2,3,5,6-tetrachloro-1,4-benzoquinone (chloranil = CHL) and σ-acceptor iodine (I 2 ) have been studied spectrophotometrically in chloroform at room temperature by electronic and infrared spectra as well as elemental and thermal analysis. The obtained results indicate the formation of 1:3 M ratio for 1MPIPZ with TCNQ and TCNE, and 1:1 M ratio for 1MPIPZ with DDQ, CHL, and I 2 . Based on the obtained data, the formed charge-transfer complexes were formulated as [(1MPIPZ)(TCNQ) 3 ], [(1MPIPZ) (TCNE) 3 ], [(1MPIPZ)(DDQ)], [(1MPIPZ)(CHL)] and [(1MPIPZ) 2 I] + I 3 - .
