Four pyridine derivatives copper halide complexes were designed and synthesized.The main contents and results of this thesis are as follows:1.Complex C₁₁H₁₀N₂Cu₂Br₃(1)(C₂₂H₂₀N₄=1,1"-(1,2-ethanediyl)-bis-4,4'-bipyridinium)was synthesized via microwave-assisted solvo-thermal reaction of C₂₂H₂₀N₄Br₂,Cu SO₄·5H₂O and Na Br,and characterized by XRD,FTIR,thermogravimetric analysis,and so on.C₁₁H₁₀N₂Cu₂Br₃ crystallizes in the monoclinic space group C2/c(no.15)with lattice parameters a=24.658(3)?,b=6.71(9)?,c=17.368(9)?,?=98.274(1)°,V=2847.7(1)?³,Z=8.Complex 1 shows a 2-D layered structure composed of[Cu₂Br₃]^–chains connected via 1,1"-(1,2-ethanediyl)-bis-4,4'-bipyridinium ligands.The thermogravimetric analysis indicates that complex C₁₁H₁₀N₂Cu₂Br₃ is stable up to 230 ^oC,and the final decomposition product is copper.2.Complex C₂₂H₂₀N₄Cu₈I₁₀(2)(C₂₂H₂₀N₄=1,1"-(1,2-ethanediyl)-bis-4,4'-bipyridinium)was synthesized via solvo-thermal reaction of C₂₂H₂₀N₄Br₂,Cu SO₄·5H₂O and Na I,and characterized by XRD,FTIR,and thermogravimetric analysis.The crystal structures were determined by single-crystal X-ray diffraction analyses.C₂₂H₂₀N₄Cu₈I₁₀crystallizes in the monoclinic space group P2₁/n(no.14)with lattice parameters a=7.392(2)?,b=20.809(7)?,c=25.412(7)?,?=92.06(8)°,V=3906.6(8)?³,Z=4.Complex C₂₂H₂₀N₄Cu₈I₁₀ possesses a 3-D framework in which puckered[Cu₈I₁₀]^2–layers are linked by organic ligands.The thermogravimetric analysis indicates that complex C₂₂H₂₀N₄Cu₈I₁₀is stable up to 170 ^oC.3.Complex C₁₁H₁₀N₂Cu₂I₃(3)crystallizes in the monoclinic space group C2/c(no.15)with lattice parameters a=24.802(3)?,b=6.9132(9)?,c=17.738(2)?,?=98.493(3)°,V=3008.0(6)?³,Z=8.The crystal structure of complex C₁₁H₁₀N₂Cu₂I₃ is isostructural with complex C₁₁H₁₀N₂Cu₂Br₃.4.Complex C₂₈H₂₄N₄Cu O₁₃S₂(4)crystallizes in the triclinic space group P^–1(No.2),with lattice parameters a=10.682(1)?,b=12.829(1)?,c=13.496(1)?,?=97.74(3)°,?=111.0(2)°,?=111.0(2)°,V=1535.9(2)?³,Z=2.Each Cu ion is coordinated by two N from organic ligands and two“SO₄^2-”to form a[Cu O₁₀S₂]^2-cluster,each[Cu O₁₀S₂]^2-cluster is connected via 1,1"-(?,?'-p-xylene)-bis-4,4'-bipyridinium ligands to form a flyover structure.
