A novel coordination polymer [(Cu 4 I 6 )(BPE)] n (BPE = 1, 2-bis(pyridinium) ethane dication) is obtained and characterized by X-ray crystallography and IR spectroscopy. The complex crystallizes in monoclinic system, space group C2(1)/c with cell parameters of a = 16.5429(19)Å, b = 10.0645(12)Å, c = 11.7139(13) A, α = 90.00 • , β = 99.0910(10) • , γ = 90.00 • . In the polymeric framework, [Cu 4 I 6 ] n dimers are bridged together by the two µ 2 -I ligands to constitute an infinite 1D chain with the organic dication BPE trapped in it. Photoluminescence investigation of the complex reveals that a red shift of 67 nm for the complex takes place, compared with the organic dication.
