| Abstract: | Metallica : A large contraction of the Pt? Pt bond in the triplet excited state of the photoreactive [Pt2(P2O5H2)4]4? ion is determined by time‐resolved X‐ray absorption spectroscopy (see picture). 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.  |
