According to spectroscopic (NMR, IR, UV/Vis) study, the interaction of pentaphosphaferrocene [Cp*Fe(η 5 ‐P 5 )] with trimeric copper pyrazolate [(Cu{3,5‐(CF 3 ) 2 Pz}) 3 ] yields a new compound that is astonishingly stable in solution. Single‐crystal X‐ray analysis reveals unprecedented structural changes in the interacting molecules and the unique type of coordination [Cp*Fe(μ 3 ‐η 5 :η 2 ,η 2 ‐P 5 ){Cu(3,5‐(CF 3 ) 2 Pz)} 3 ]. As a result of the 90° macrocycle folding, the copper atoms are able to behave both as a Lewis acid and as a Lewis base in the interaction with the cyclo‐P 5 ligand.
