Abstract

Metallica: A large contraction of the PtPt bond in the triplet excited state of the photoreactive [Pt~2~(P~2~O~5~H~2~)~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.magnified image

## Abstract Cathelicidins comprise a major family of host‐defense antimicrobial peptides in vertebrates. The C‐terminal part of the cathelicidins is bestowed with antimicrobial and lipopolysaccharide (LPS) neutralizing activities. In this work, we repot high resolution solution structures of two no
