Reactions of Cu + containing the weakly coordinating anion [Al{OC(CF 3 ) 3 } 4 ] − with the polyphosphorus complexes [{CpMo(CO) 2 } 2 (μ,η 2 :η 2 ‐P 2 )] ( A ), [CpM(CO) 2 (η 3 ‐P 3 )] (M=Cr( B1 ), Mo ( B2 )), and [Cp*Fe(η 5 ‐P 5 )] ( 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 [Cu 2 ( C ) 3 ] 2+ paddle‐wheel building block. All products are readily soluble in CH 2 Cl 2 and exhibit fast dynamic coordination behavior in solution indicated by variable temperature 31 P{ 1 H} NMR spectroscopy.
