Abstract:
The SCF-Xα-SW method has been applied to the fine structure in x-ray L absorption spectra for the metal near the ionization thresholds in [PdCI4] 2-, [PtCI4] 2-,[PdCI6] 2-, and [PtCI6] 2- clusters, which simulate solid-state coordination compounds such as K2PdCI4. Synchrotron radiation has been used to record the L3 absorption spectra for Pt in K2PtCI4 and K2PtCI 6. It is found that the subthreshold white line and the immediate fine structure (XANES) in the L 3 spectra for Pd and Pt in square and octahedral chloride complexes are due to electron excitation to a vacant bound molecular orbital (eg for the octahedral compounds and b1g for the square ones) below the ionization threshold and to resonant elastic photoelectron scattering at the metal atom and at the atoms in the first coordination sphere above the threshold correspondingly. The calculations indicate that the L 1 metal spectra for these compounds do not have strong subthreshold transitions, while the XANES is produced by several strong narrow resonances with t1u symmetry for the
octahedral compounds or a2u and e u for the square ones.
