Phosphonium‐Substituted Diphosphaindenylide (PPI): Exploration of Biradical Character and Ligand Properties

Invited for the cover of this issue is the group of Peter Coburger at the Technical University of Munich. The image, painted by Dr. Christoph Selg, depicts the bonding relationships in a biradicaloid chromium complex as a staircase, with the people symbolizing the two‐way flow of electrons between the ligand and the metal.
