Compounds K3[MX2(SO3)2H/D] (M = Pd, Pt; X = Cl, Br) with very short intramolecular hydrogen bonds O..H/D..O (bond lengths R(O....O) < 240 pm) were studied with IR, Raman, and, partly, inelastic neutron scattering spectrometries at ambient and low temperatures. On this experimental basis, the hydrogen-bond vibrations in the unusual sequence delta(OHO) > gamma(OHO) > nu(as)(OHO) are assigned to bands around 1500, 950, and 750 cm-1, respectively; the latter shows a complex structure (IR spectrum) and abnormal isotope shift with nu(H)/nu(D) close to 1. These vibrations are not strictly localized, but couple with modes of the SO3 ligands. Slow rocking modes of the SO3 ligands involving protons occur around 350 and 250 cm-1. In contrast, the vibrations of the medium-strong intermolecular hydrogen bonds in [RU(SO3H/D)2(NH/D3)4] (R(O....O) 268.9 pm) behave normally with nu(as)(OHO) 2950, delta(OHO) 1240, and gamma(OHO) 700 cm-1/100 K, all with isotope shift ratios near 1.35.
