Bimetallic Complexes. NMR, IR, and UV/Vis spectroscopic analyses indicate that pentaphosphaferrocene [Cp*Fe(η 5 ‐P 5 )] and trimeric copper pyrazolate [(Cu{3,5‐(CF 3 ) 2 Pz}) 3 ] interact to form a new compound that is astonishingly stable in solution, as reported by E. S. Shubina et al. in their Communication on page 13176 ff. Furthermore, single‐crystal X‐ray analysis reveals unprecedented structural changes in the interacting molecules and a unique type of coordination in the resultant [Cp*Fe(μ 3 ‐η 5 :η 2 ,η 2 ‐P 5 ){Cu(3,5‐(CF 3 ) 2 Pz)} 3 ] complex. 90° folding of the trimeric copper macrocycle enables the copper atoms to behave both as Lewis acid and Lewis base in the interaction with the cyclo‐P 5 ligand.
