Die IR-Spektren der Hexaoxoplatinate(IV) und -rhenate(VII)

The infrared spectra of the hexaoxoplatinates(IV) and -rhenates(VII)

  • Several oxoplatinates (IV) and -rhenates (VII) with isolated PtO6 or ReO6 octahedra respectively surrounded by lithium, sodium, magnesium, calcium, strontium and barium atoms were prepared. From infrared spectra (KBr pellet technique) force constants were calculated. The values varied. depending on an inductive field effect caused by the alcaline and alcaline earth atoms, which increased in the following order: Ba<Sr<Ca ≈ ≪ Mg. By means of bond order it can be predicted that for central atoms with d0 or d10 configuration and with an oxidation state lower than six only such hexaoxometallates will be formed in which the alcaline or alcaline earth atoms intensity the force constant by a strong inductive effect. PtO6 requires an additional force which lowers the symmetry of PtO6 and stabilizes the hexaoxoplatinates (IV).
