A Novel Adduct of TCNQ Dianion with Schiff-Base Cobalt(III) Complex in N-Bonded Coordination Mode in Dmf Solution [TCNQ = 7,7,8,8-Tetracyanoquinodimethane]

Formation of a stable novel adduct, [Co(III)(saloph)]2 TCNQ(-II), has been confirmed by analysis of the 1H NMR spectra of the N,N-dimethylformamide(dmf)-acetonitrile solution of LiTCNQ and [N,Nʹ-o-phenylenebis(salicylideneaminato)] cobalt(II), denoted as [Co(II)(saloph)]. The time-resolved spectra of the UV-vis absorption of the LiTCNQ-[Co(II)(saloph)] solutions gave information concerning the formation process of the adduct.
