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。
One new copper with one-dimensional double-stranded structure was synthesized by the reaction of highly flexible bistriazole ligand (1,2- (1H-1,2,4-triazole)) ethane (Ⅱ) complex {[Cu (cis-L) 2Br] Br.2H2O} n (1). The single crystal structure shows that the crystal of complex 1 belongs to triclinic system, space group P1. In the complex 1, the bis-triazole ligand adopts the trans configuration and bridges the adjacent central copper ions to form a one-dimensional double-stranded structure. The free Br atoms in the lattice form a four-membered ring with the coordination water Br ... O supramolecular ring. The magnetic susceptibility of complex 1 at 2 ~ 300 K was measured. The results showed that there was a weak antiferromagnetic interaction between adjacent copper ions.
