Synthesis, Luminescence, and Electrochemistry of Mix-Capped Trinuclear Copper(I) Acetylide Complexes. X-ray Crystal Structures of Cu3(μ-dppm)3(μ3-η1-C⋮CC6H4OMe-p)(μ3-η1-C⋮CC6H4OEt-p)PF6 and Cu3(μ-dppm)3(μ3-η1-C⋮CC6H4OMe-p)(μ2-η1-C⋮CC6H4NO2-p)PF6

Two luminescent mix-capped trinuclear copper(I) acetylide complexes, Cu3(μ-dppm)3(μ3-η1-C⋮CC6H4OMe-p)(μ3-η1-C⋮CC6H4OEt-p)PF6 (1) and Cu3(μ-dppm)3(μ3-η1-C⋮CC6H4OMe-p)(μ2-η1-C⋮CC6H4NO2-p)PF6 (2), have been synthesized and their photophysical and electrochemical properties studied. The X-ray crystal structures of 1 and 2 have also been determined.
