The far infrared spectra of tetrahalogenozincate(II) complexes with mixed halide ligands

Abstract

The far infrared spectra (400-40 cm^-1) of the complexes (MePh₃As)₂ ZnBr_nCl_4-n (n = 0, 1, 2, 3, or 4), (Et₄N)₂ZnBr_nCl_4-n (n = 1, 2, or 3), (Me₄N)₂ZnBr₂Cl₂, (pyH)₂ZnBr₂Cl₂, (Et₄N)₂ZnBr_nI_4-n (n = 0, 1, 2, 3, or 4), and (Et₄N)²ZnCl_nI_4-n (n = 1 or 2) have been recorded. Vibrational assignments have been made for the zinc-halogen frequencies and the spectra are discussed in terms of known or probable structures.
