We present the first structural detn. of the Pt2(P2O5H2)44- anion in soln. by analyzing the extended X-ray absorption fine structure (EXAFS) spectrum of the Pt LIII edge. The data could be fit with a simple model involving single and multiple scattering paths to near and far P-atoms, bridging O-atoms, and the other Pt-atom in the binuclear complex. A Pt-Pt distance of 2.876(28) .ANG. and a Pt-P bond length of 2.32(4) .ANG. are obtained. These values are in line with distances found in previous… Expand
L-edge XANES analysis of photoexcited metal complexes in solution.
The improved theoretical treatment of inelastic losses has shown to result in more accurate peak positions in the above-continuum region of the spectrum which is an important prerequisite for obtaining quantitative structural information from (time-resolved) XANES spectra. Expand
Time-resolved X-ray scattering of an electronically excited state in solution. Structure of the 3A(2u) state of tetrakis-mu-pyrophosphitodiplatinate(II).
The structure of the (3)A(2u) excited state of tetrakis-mu-pyrophosphitodiplatinate(II) in aqueous solution is investigated by time-resolved X-ray scattering and it is found that a slight lengthening of the Pt-P bond occurs following excitation. Expand
Theoretical study of the triplet excited state of PtPOP and the exciplexes M-PtPOP (M = Tl, Ag) in solution and comparison with ultrafast X-ray scattering results
Abstract The [Pt 2 (H 2 P 2 O 5 ) 4 ] 4− ions in the ground and excited states and the excited-state complexes M-[Pt 2 (H 2 P 2 O 5 ) 4 ] 3− and M 2 -[Pt 2 (H 2 P 2 O 5 ) 4 ] 2− (M = Ag, Tl) wereExpand
X-ray absorption spectroscopy of ground and excited rhenium-carbonyl-diimine complexes: evidence for a two-center electron transfer.
It is demonstrated that the transient spectra at both the Re L(3)- and Br K-edges show the emergence of a pre-edge feature, absent in the ground-state spectrum, which is associated with the electron hole created in the highest occupied molecular orbital following photoexcitation. Expand
Retrieving photochemically active structures by time-resolved EXAFS spectroscopy
Describing the nature and structure of molecular excited states is important in order to understand their chemical reactivity and role as intermediates in photochemical reactions. The recentExpand
Structural determination of a photochemically active diplatinum molecule by time-resolved EXAFS spectroscopy.
The strengthening of the Pt-Pt interaction is accompanied by a weakening of the ligand coordination bonds, resulting in an elongation of the platinum-ligand bond that is determined for the first time by time-resolved X-ray absorption spectroscopy. Expand
Ultrafast Intersystem Crossing and Structural Dynamics of [Pt(ppy)(μ-tBu2pz)]2.
This work investigates the case of the prototypical d8-d8 dimetal complex [Pt(ppy)(μ-tBu2pz)]2 using broad-band transient absorption anisotropy in combination with ultrafast fluorescence up-conversion and ab initio calculations to demonstrate the relationship between the energy relaxation and structural dynamics of this molecule.

Simulations of X-ray absorption spectra: the effect of the solvent.
This work performs quantum mechanics/molecular mechanics molecular dynamics simulations on the PtPOP complex in water, dimethylformamide and ethanol to show a significant solvent effect on the spectra, which has important implications for the structural analysis of molecules in solution. Expand
