Infared investigation of aromatic and aliphatic dithioacids as ligands. Part I. Metal dithiobenzoates
Abstract
I.r. spectra are reported for a series of dithiobenzoato-complexes of divalent (NiII, PdII, and PbII) and trivalent (CrIII, FeIII, RhIII, and InIII) metals and of some of their deuteriated analogues. The two stretching frequencies of the dithiocarboxylic group have been located in the range 900–1000 cm–1, and the metal-sulphur stretchings between 300 and 400 cm–1. The regular decrease of the highest substituent–sensitive frequency of the phenyl group with the optical electronegativity of the chelated metal ion is discussed.
