Vibrational spectra of complexes of mercury(I) and mercury(II) with pyridine and other nitrogen bases

Abstract

Raman and i.r. spectra of the series of compounds MeHg(pyx)ClO₄, Hg(pyx)_n(ClO₄)₂ and Hg₂^- (pyx)_n(ClO₄)₂ (pyx = pyridine or a pyridine derivative; n = 2 or in some cases 4) are reported. In the low- frequency region, the spectra of the complex cations provide the basis of assignments of Hg-N (160-260 cm^-1) and Hg-Hg (110-160 cm^-1) stretching frequencies.
