Electron spin resonance and electronic spectra of some silver hexafluorometallates(IV) and metal(II) tetrafluoroargentates(II)
Abstract
E.s.r. and diffuse-reflectance spectra have been obtained for the compounds AgMF6(M = Sn, Ph, Hf, or Zr) and MAgF4(M = Ba, Ca, Hg, or Sr). The data indicate that all the compounds studied contain the silver(II) ion in either an axially elongated tetragonal or a square-planar arrangement. Possible assignments for the electronic-absorption bands are discussed.
