Abstract: In the title complex, [Cu(C₂₀H₁₃BrN₄)(C₁₈H₁₅P)₂]BF₄·0.5CH₂Cl₂, the copper(I) cation adopts a distorted tetrahedral arrangement, coordinated by two triphenylphosphine ligands and two N atoms of the potentially tridentate terpyridine ligand. One half-molecule of dichloromethane crystallizes with the complex. The chlorine atoms are disordered over two sites with occupancies fixed at 0.30 and 0.20 respectively. The N donor atom of the central pyridine interacts weakly with the copper centre at a distance of 3.071 Å.
