Unusual Coordination Behaviour of Pn-Ligand Complexes with Tl+ [Ungewöhnliches Koordinationsverhalten von Pn-Ligandkomplexen gegenüber Tl+]

Zusammenfassung

Pentaphosphaferrocene coordinates as a ligand to the large monocation Tl+. In addition, one of the phosphorus atoms of each cyclo-P5 moiety coordinates to a neighboring Tl+ ion to give a one-dimensional polymer. Even at low temperatures, fast rotation of the P5 rings is observed in solution and in the solid state.
