The strengthening of the PtPt 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.optical spectroscopystructure elucidationtime-resolved spectroscopytriplet statesX-ray absorption spectroscopyRay-Absorption SpectroscopyTriplet Excited-StateSublevel Phosphorescence SpectraTransition-Metal-ComplexesX-RayBinuclear Platinum(Ii)Photophysical PropertiesElectronic SpectroscopyEnergy-TransferPt2(P2O5H2)44text::journal::journal article::research article
