摘要:
A novel coordination polymer [(Cu4I6)(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) angstrom, b = 10.0645(12) angstrom, c = 11.7139(13) angstrom, = 90.00 degrees, = 99.0910(10)degrees, = 90.00 degrees. In the polymeric framework, [Cu4I6]n dimers are bridged together by the two 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.
