乙酸根与1，6-二(1H-1，2，4-三唑)己烷交替桥联的一维Cu(Ⅱ)配位聚合物

Using a new ligand 1,6-bis(1,2,4-triazole-1-yl)hexane (L), one-dimensional coordination polymer [Cu₂(L)(CH₃CO₂)₄]_n has been synthesized and characterized by elemental analysis, FTIR spectra and X-ray single crystal structural analysis. The title complex crystallizes in triclinic system with space group P1, a=0.722 5(7) nm, b=0.808 0(8) nm, c=1.173 1(11) nm, α=72.294(11)°, β=88.049(11)°, γ=66.294(11)°, V=0.594 2(10) nm³, Z=1, R₁=0.037 0, wR₂=0.098 3. The fundamental unit comprises two copper atoms (Cu(1), Cu(1A)), four μ₂-bridged CH₃CO₂^- and one ligand molecule. Cu(1) and Cu(1A) are both five-coordinated by four oxygen atoms from four μ₂-CH₃CO₂^- and one nitrogen atom from bridging ligand, forming a distorted square-pyramidal coordination configuration. Cu(1) and Cu(1A) are linked via four μ₂-bridged CH₃CO₂^- anions to form a paddle-wheel structural unit, which furthermore self-assemble into 1D chain via bridging ligands. CCDC: 603429.
