Infrared investigation on aromatic and aliphatic dithio-acids as ligands. Part 2. The infrared spectra of bis(trithioperoxybenzoato)-zinc(II)(polarised) and -nickel(II)

Abstract

Infrared band assignments for bis(trithioperoxybenzoato)zinc(II)[Zn(S₃CPh)₂], are reported, based on polarisation measurements on polycrystalline iso-orientated samples. The results confirm most of the assignments previously proposed for dithiobenzoatometal complexes and strongly support the assignment of ν(S–S) to a weak absorption at 655 cm^–1. The spectral comparison with the corresponding nickel compound and analogous compounds is discussed.
