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.
