Remarkable Structural and Electronic Features of the Complex Formed by Trimeric Copper Pyrazolate with Pentaphosphaferrocene.
According to spectroscopic (NMR, IR, UV/Vis) study, the interaction of pentaphosphaferrocene [Cp*Fe(η(5) -P5 )] with trimeric copper pyrazolate [(Cu{3,5-(CF3 )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(μ3 -η(5) :η(2) ,η(2) -P5 ){Cu(3,5-(CF3 )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-P5 ligand.
