The synthesis and crystal structure of a new one-dimensional mixed-ligand Cu(I) coordination polymer, [(PPh3)2Cu2(μ-I)2(μ-4, 4′bpy)]n (4,4′-bpy = 4,4′-bipydine) are reported. The neutral polymer consists of (PPh3)2Cu2(μ-I)2(μ-4, 4′-bpy) units bridged by 4,4′-bpy to construct an infinite chain architecture. Crystal data: C23H19CuINP, Mr = 530.80, Triclinic space group (P1, No. 2), a = 9.2279(8) A?, b = 9.4014(8) A?, c = 13.3663(12) A?, α = 107.445(2)°, β = 106.707(2)°, γ = 93.479(2)°, V = 1045.8(2) A?3, Dcalc = 1.686 g m-3, Z = 2. The solid state of the complex is luminescent with a peak maximum at 535 nm, upon excitation at 300-400 nm at room temperature. The emission is assigned to Copper(I) to 4,4′-bpy charge transfer (MLCT).
