摘要：

The synthesis and characterization of [Cu3-(C =CPh)2(Ph2PCH2PPh2)3][BF4] (1), the first cationic trinuclear copper(I) complex bicapped by two bridging-delta-bonded phenylacetylide groups, is described. An X-ray single-crystal structure determination shows that the two linear phenylacetylide groups are bonded in a mu-3-eta-1 fashion, representing an unprecedented structure in organocopper(I) chemistry. The electronically deficient bonding can be formally described as a five-center-four-electron system.
