Three polymeric copper(I) halide complexes bearing 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 synthe-sized 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),α=106.440(4),β=105.965(5),γ=94.167(5)°,V=1021.3(6) 3,Mr=967.62,Z=1,Dc=1.573 g/cm3,F(000)=486,μ=3.111 mm-1,the final R=0.0383 and wR=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),α=104.136(6),β=108.132(5),γ=95.338(6)°,V=1081.0(7) 3,Mr=496.83,Z=2,Dc=1.526 g/cm3,F(000)=500,μ=2.941 mm-1,the final R= 0.0445 and wR=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),α=109.57(3),β=93.85(3),γ= 97.28(3)°,V=1242(4) 3,Mr=1074.59,Z=1,Dc=1.436 g/cm3,F(000)=548,μ=1.279 mm-1,the final R=0.0786 and wR=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.
