title: Highly dynamic coordination behavior of Pn ligand complexes towards "naked" Cu(+) cations.
abstract: Reactions of Cu(+) containing the weakly coordinating anion [Al{OC(CF3 )3 }4 ](-) with the polyphosphorus complexes [{CpMo(CO)2 }2 (μ,η(2) :η(2) -P2 )] (A), [CpM(CO)2 (η(3) -P3 )] (M=Cr(B1), Mo (B2)), and [Cp*Fe(η(5) -P5 )] (C) are presented. The X-ray structures of the products revealed mononuclear (4) and dinuclear (1, 2, 3) Cu(I) complexes, as well as the one-dimensional coordination polymer (5 a) containing an unprecedented [Cu2 (C)3 ](2+) paddle-wheel building block. All products are readily soluble in CH2 Cl2 and exhibit fast dynamic coordination behavior in solution indicated by variable temperature (31) P{(1) H} NMR spectroscopy.
