Abstract A series of soluble trinuclear and tetranuclear copper(I) complexes containing μ3-ηl acetylides $$[{\text{Cu}}_{\text{3}} (\mu {\text{ - dppm}})_3 (\mu _3 {\text{ - }}\eta ^{\text{1}} {\text{ - C}} \equiv {\text{CR}})]^{2 + } ,[{\text{Cu}}_{\text{3}} (\mu {\text{ - dppm}})_3 (\mu _3 {\text{ - }}\eta ^{\text{1}} {\text{ - C}} \equiv {\text{CR}})_2 ]^ + $$ , and $$[{\text{Cu}}_{\text{4}} ({\text{PPh}}_{\text{3}} )_4 (\mu _3 {\text{ - }}\eta ^{\text{1}} {\text{ - C}} \equiv {\text{CR}})_4 ]$$ have been synthesized and shown to exhibit rich photoluminescent behavior at room temperature. The electrochemistry of the trinuclear Cu(I) acetylide complexes and the excited-state redox properties of $$[{\text{Cu}}_{\text{3}} (\mu {\text{ - dppm}})_3 (\mu _3 {\text{ - }}\eta ^{\text{1}} {\text{ - C}} \equiv {\text{CC}}_{\text{6}} {\text{H}}_{\text{4}} {\text{OMe - }}p)_2 ]^ + $$ have been investigated. The X-ray crystal structures of $$[{\text{Cu}}_{\text{3}} (\mu {\text{ - dppm}})_3 (\mu _3 {\text{ - }}\eta ^{\text{1}} {\text{ - C}} \equiv {\text{CC}}_{\text{6}} {\text{H}}_{\text{4}} {\text{OMe - }}p)_2 ]^ + $$ and $$[{\text{Cu}}_{\text{4}} ({\text{PPh}}_{\text{3}} )_4 (\mu _3 {\text{ - }}\eta ^{\text{1}} {\text{ - C}} \equiv {\text{CC}}_{\text{6}} {\text{H}}_{\text{4}} {\text{OMe - p}})_4 ]$$ have been determined.
