title: Synthesis of some new o-thioazo ligands and evaluation of their metallochromic properties.
abstract: The synthesis of several new o-thioazo derivatives of p-cresol and 2-naphthol is reported, as well as their spectral properties, acid dissociation constants, and potential as metallochromic reagents. All the ligands form complexes with CU(2+) and Ni(2+). o-Mercaptoazo complexes of Fe(3+) and Cu(2+) with molar absorptivities of 3.83 x 10(4) and 3.58 x 10(4) l.mole(-1) cm(-1), respectively, are described.
