A binuclear Cu(I) complex [Cu(PCNP)(mepypz)]₂(BF₄)₂ (1, PCNP = 2,6-bis(diphenylphosphine)-benzonitrile, mepypz = 2-(1H-pyrazol-3-yl)pyridine) was synthesized from the reaction of Cu(CH₃CN)₄BF₄, PCNP and mepypz in CH₂Cl₂ at room temperature. The compound was characterized by NMR, UV-vis and X-ray single-crystal structure analysis. It crystallizes in monoclinic space group P2₁/c with a = 14.0139(5), b = 11.8149(3), c = 27.1248(10) Å, β = 96.686(4)°, V = 4460.6(3) ų, Z = 2, M_r = 1561.97, D_c = 1.163 g/cm³, F(000) = 1600.0, μ = 1.774 mm^–1, GOOF = 1.071, the final R = 0.0523 and wR = 0.1412 for 7919 observed reflections with I > 2σ(I). The Cu atoms in the complex are four-coordinated and adopt a distorted tetrahedral coordination geometry. In the solid state, the complex exhibits yellowish-green emission with a peak wavelength of 546 nm, a lifetime of 390 μs, and a quantum yield of 0.45 at room temperature. The temperature-dependent investigation of luminescent properties suggests that the complex emits thermally activated delayed fluorescence (TADF) at room temperature.
