The synthesis and characterization of the novel 2,3- dithiolatoterephthaldiamide ligands C6H2{C(O)NHBn} 2(SH)2 (H2-1a) and C6H 2{C(O)NH-iP:r}2(SH)2 (H2-Ib) as well as their complexes with NiII, CoIII, and FeIII is described. The molecular structures of the complexes (NEt 4)[Co(1a)2], (AsPh4h2[Ni(1b) 2]·dmf, and (AsPh4)[Fe(1a)2]·CH 2Cl2 were determined by single-crystal X-ray diffraction. Electronic absorption spectroscopy and cyclic voltammetry were applied to investigate the electronic properties of the complex anions [M(L) 2]n-(M = Ni, Co; L = 1a, 1b; n = 1, 2). Comparison of the structural and electronic characteristics of the complexes with ligands 1a 2- and 1b2- to those of the corresponding complexes with related benzene-o-dithiolato ligands indicates a notable influence of intramolecular N-H... S hydrogen bonding between amide protons and coordinated sulfur atoms in 2,3-dithiolatoterephthalamide complexes.
