In the title heteroleptic cuprous complex, (acetonitrile‐κ N )({2‐[2‐(diphenylphosphanyl)phenoxy]phenyl}diphenylphosphane‐κ 2 P , P ′)[2‐(pyridin‐4‐yl‐κ N )‐1,3‐benzoxazole]copper(I) hexafluoridophosphate, [Cu(C 36 H 28 OP 2 )(CH 3 CN)(C 12 H 8 N 2 O)]PF 6 , conventionally abbreviated [Cu(POP)(CH 3 CN)(4‐PBO)]PF 6 , where POP is the diphosphane ligand {2‐[2‐(diphenylphosphanyl)phenoxy]phenyl}diphenylphosphane and 4‐PBO is the N‐containing ligand 2‐(pyridin‐4‐yl)‐1,3‐benzoxazole, the asymmetric unit consists of a hexafluoridophosphate anion and a whole mononuclear cation, where the Cu I centre is coordinated by two P atoms from the POP ligand, by one N atom from the 4‐PBO ligand and by the N atom of the coordinated acetonitrile molecule, giving rise to a CuP 2 N 2 distorted tetrahedral coordination geometry. The electronic absorption, photoluminescence and thermal stability properties of this complex have been studied on as‐synthesized samples, which had previously been examined by powder X‐ray diffraction. A yellow emission signal is attributed to an excited state arising from metal‐to‐ligand charge transfer (MLCT).
