[Synthesis and luminescence spectrum of trinuclear copper(I) complex].

The novel luminescent trinuclear copper( I ) complex [Cu3 (dppm)3 (NO3) (OH)] (NO3) has been obtained by treating binuclear copper(I) [Cu(dppm) (NO3)]2 with sodium tetraphenyl boron (dppm = Ph2 PCH2 PPh2). The complex was characterized by physico-chemical and spectroscopic methods. The title complex exhibits photoluminescence behavior at room temperature.
