Front Cover: Copper(I) and Gold(I) Complexes of Aminofunctionalized Phosphinines: Synthesis and Structural Characterization (Z. Anorg. Allg. Chem. 6‐7/2023)

The cover picture shows the solid-state structure of an unusual Cu4-rhombus, which is capped by a total of four chlorido ligands. Two aminofunctionalized, aromatic phosphinines coordinate in the classical σ-coordination mode via the phosphorus lone pair to two of the four Cu(I) centers. The other two phosphinines show a rare bridging μ2-coordination mode and span two of the four Cu(I) centers. (DOI: 10.1002/zaac.202200365).
