Three polymeric copper（Ⅰ） halide complexes beating phosphine and N-donor bridging ligands, [（PPh3）2Cu2（μ-Br）2（μ-4,4＇-bipy）]∞ 1 （bipy = bipyridine）, [（PPh3）2Cu2（μ-Br）2（μ- bpe）]∞ 2 （bpe = trans-1,2-bis（4-pyridyl）ethene） and [（PPh3）2Cu2（μ-Cl）2（μ-bpe）]∞ 3, were synthesized by the multilayer diffusion method, and the structures were refined by single-crystal X-ray diffraction. Complex 1 crystallizes in triclinic, space group P1^- with a = 9.122（3）, b = 9.322（3）, c = 13.201（4） A, α = 106.440（4）, β= 105.965（5）, γ= 94.167（5）°, V = 1021.3（6） A^3, Mr= 967.62, Z = 1, De= 1.573 g/cm^3, F（000） = 486, μ = 3.111 mm^-1, the final R = 0.0383 and ωR = 0.0960 for 2792 observed reflections （I 〉 2σ（I））. Complex 2 crystallizes in triclinic, space group P1^- with a = 9.420（3）, b = 10.209（4）, c = 12.407（4） A, α = 104.136（6）, β = 108.132（5）, γ= 95.338（6）°, V = 1081.0（7） A^3, Mr= 496.83, Z = 2, Dc= 1.526 g/cm^3, F（000） = 500, μ = 2.941 mm^-1, the final R = 0.0445 and ωR = 0.1117 for 3251 observed reflections （I 〉 2σ（I））. Complex 3 crystallizes in triclinic, space group P1^- with a = 8.32（1）, b = 11.53（2）, c = 13.94（3） A, α = 109.57（3）, β= 93.85（3）, γ= 97.28（3）°, V= 1242（4） A^3, Mr= 1074.59, Z = 1, Dc = 1.436 g/cm^3, F（000） = 548, μ = 1.279 mm^-1, the final R = 0.0786 and ωR = 0.1586 for 2266 observed reflections （I 〉 2σ（I））. The complexes exhibit intensive solid-state photoluminescence tentatively assigned to an admixture of triplet intraligand （IL） and metal-to-ligand charge-transfer （MLCT） excited state.
