摘要
Solvent dependent assembly obtained two novel Ni coordination polymers with H_2 tbtpa and flexible 1,2-bix ligand(H_2tbtpa = tetrabromoterephthalic acid and 1,2-bix = 1,2-bis(imidazol-1-ylmethyl)benzene),formulated as [Ni_(0.5)(tbtpa)_(0.5)(1,2-bix)·(H_2O)]_n(1) and [Ni(tbtpa)(1,2-bix)(H_2O)_2]_n(2).They have been structurally characterized by single-crystal and powder X-ray diffraction,elemental analysis,FT-IR spectra and TGA.Compound 1 crystalizes in triclinic,space group P1 with a = 9.0276(4),b = 10.0012(6),c = 11.4955(5) A,α = 69.121(5),β = 76.398(4),γ = 89.668(4)o,C_(36)H_(32)Br_4 Ni N_8O_6,Mr = 1051.04,V = 939.05(8) A^3,Z = 1,Dc = 1.859 g·cm^-3,μ = 6.222 mm^-1,F(000) = 520,8.502≤2θ≤134.16°,λ(Cu Kα) = 1.54184 A,T = 294(6) K,the final R = 0.0750,w R = 0.1988 and S = 1.033.Compound 2 crystalizes in triclinic,space group P1 with a = 11.1257(7),b = 11.5062(6),c = 12.3529(4) A,α = 88.861(3),β = 84.572(4),γ = 64.235(6)o,C_(22)H_(18)Br_4 Ni N_4O_6,Mr = 812.75,V = 1417.36(1) A^3,Z = 2,Dc = 1.904 g·cm^-3,μ = 7.968 mm^-1,F(000) = 788,7.2≤2θ≤134.1°,λ(Cu Kα) = 1.54184 A,T = 294(6) K,the final R = 0.0414,w R = 0.0865 and S = 1.025.1 shows a two-dimensional(4,4)-sql topology and 2 manifests a three-dimensional 6~58 Cd SO_4 topology coordination polymer network.
