Abstract

New dinuclear copper(I) complexes [Cu₂(μ-X) ₂(μ-1,8-naphthyridine)-(PPh₃)₂] (X = I, Br) having the butterfly-shaped {CU₂(M-X)₂} unit show red phosphorescence at room temperature in the solid state. Molecular orbital calculations show that the emissions of the new complexes are not directly related to their short Cu⋯Cu separations [2.6123(5) and 2.6271(4) Å] and are assignable to the triplet charge-transfer excited states from the {CU₂(μ-X)₂} core to 1,8-naphthyridine.
