| Synthesis and Characterization of One Novel 1D Double-Chain Copper(Ⅱ) Complex with 1,2-Bis(1,2,4-triazole-1-yl)ethane | |
| 摘要: 利用高度柔性的双三唑配体(1，2-(1H-1，2，4-三唑))乙烷(L)和铜盐反应合成了1个新的具有一维双链结构的铜(Ⅱ)配合物{[Cu(cis-L)2Br]Br·2H2O}n(1)。单晶结构表明：配合物1的晶体属于三斜晶系，P1 空间群。在配合物1中双三唑配体采用反式构型，桥联相邻的中心铜离子形成一维双链结构，晶格中游离的Br原子同配位水分子形成了四元环状的Br…O超分子环。测定了配合物1在2~300 K的变温磁化率，结果表明相邻铜离子间存在弱的反铁磁相互作用。 | |

| Abstract: Using the highly flexible bis-triazole ligand 1,2-bis(1,2,4-triazole-1-yl)ethane (L), one new complex {[Cu(cis-L)2Br]Br·2H2O}n (1) has been synthesized and characterized by elemental analysis, FTIR and single crystal X-ray diffraction analysis. It belongs to triclinic system with space group P1, a=0.757 0(2) nm, b=0.877 2(3) nm, c=1.641 5(5) nm, α=104.187(5)°, β=90.905(5)°, γ=98.589(5)°, V=1.043 4(5) nm3, Z=2. In 1 two cis-L molecules bridge central copper(Ⅱ) ions forming 1D double-chain structure, four-member Br…O supra-molecular cycles can also be observed. The varied temperature magnetic property of 1 has been investigated from 300 to 2 K indicating weak anti-ferromagnetic interactions between neighboring copper(Ⅱ) ions. CCDC: 753647. | |
