Three New d~(10) Coordination Polymers with Arenedisulfonates:Syntheses,Crystal Structures and Luminescent Properties

Three new cadmium or zinc arenedisulfonate complexesZn(bpp)2(L)]n 1, {Cd(bpp)2(1,5-NDS)(H2O)2]·4H2O}n2 and{Cd(bpp)2(H2O)2]·(1,5-NDS)}n 3 (L=4,4'-bis(2-sulfo-natostyryl)biphenyl,bpp=1,3-di(4-pyri-dyl)propane and 1,5-NDS=1,5-Naphthalenedisulfonate) have been synthesized from aqueous solution and structurally characterized by infrared spectroscopy, elemental analysis and single-crystal X-ray diffraction.Crystal data for complex 1:space group P21/n, a=10.559(3),b=13.138(4),C=17.623(5)A,β=100.852(3)°,V=2400.9(12)A3,Z=2,Dc=1.351 g/cm3,F(000)=1016,μ=0.654 mm-1,the final R=0.0412 and wR=0.0994;Crystal data for complex 2:space group P1,a=8.5642(19),b=10.076(3),C=12.114(3)A,α=81.623(7),β= 77.149(8),γ=82.787(7)°,V=1003.6(4)A3,Z=1,Dc=1.495 g/cm3,F(000)=466,μ=0.713 mm-1, the final R=0.0241 and wR=0.0713;Crystal data for complex 3:space group C2/c,a=21.6024(15), b=9.4608(5),C=18.4656(11)A,A,β=107.359(3)°,V=3602.0(4)A3,Z=4,Dc=1.533 g/cm3,F(000) =1704,μ=0.780 mm-1,the final R=0.0229 and wR=0.0572.The X-ray single diffraction reveals that 1 exhibits a 3Dmetal-organic framework formed from 2D Zn(bpp)22+networks connected by Lin the tllird dimension;2 and 3 possess 3D and 2D architectures constructed from 1D polymeric chains through H-bond.Complexes 1～3 display photolumineseent emissions at 452 and 335 nm,respectively.
