Coordination of a bulky pyridinyl‐phosphine ( P˜N ) ligand toward CuBr was investigated. However, this P˜N donor behaves as a monodentate via the coordination of phosphine to form a bromide bridged dimeric [( P˜N )Cu(μ‐Br) 2 Cu( P˜N )], which was characterized by spectral and crystal structural analysis. It appeared that the “PCu(μ‐Br) 2 CuP” unit is planar with a short distance between Cu…Cu' [2.7585(9) Å]. The catalytic activity on Sonogashira coupling of phenylacetylene with aryl halides was studied.
