Coinage metal complexes of multidentate Pacman phosphane ligands

We present the extension of Pacman ligands to bidentate phosphane ligands enabling them to bind metals in their sterically protected cavity. The coordination of coinage metals shows the ability of the ligand to adopt different coordination modes by distortion, of which some additionally include the imine nitrogen atoms. Besides the coordinated metal, the substitution on the phosphorus atoms influences the type of coordination.

Automated summary

We have extended the functionality of Pacman ligands by modifying them into bidentate phosphane ligands, allowing them to bind metals in a sterically protected cavity. The coordination of coinage metals demonstrates the ligand's ability to adopt various coordination modes, with some modes including the imine nitrogen atoms as well. Furthermore, the type of coordination is influenced by the substitution on the phosphorus atoms.
