| 摘要: 水热条件下，合成了新的金属有机骨架[Cu(Hbtc)(bmix)0.5]n(1)(H3btc=1，3，5-苯三甲酸，bmix=1，4-二(2-甲基咪唑基-1-亚甲基)苯)。单晶X射线衍射分析表明，该配合物属正交晶系，Pbcn空间群，晶胞参数为a=1.436 30(9) nm，b=1.477 15(11) nm，c=1.543 48(10) nm，V=3.274 7(4) nm3，Z=8。配合物1中，Hbtc2-以四连接方式与铜中心配位，bmix桥连配体进一步修饰网络结构，最终1显示为1个(4，5)节点的三维的网络结构，其Schl?fli 符号为(42·5·62·8)(42·53·63·7·8)。此外还研究了配合物的热稳定性和对光助类芬顿反应降解甲基橙的催化性质。 |

| Abstract: A metal-organic framework [Cu(Hbtc)(bmix)0.5]n(1) (H3btc=1,3,5-benzenetricarboxylic acid, bmix=1,4-bis(2-methylimidazole-1-ylmethyl)benzene) has been hydrothermally synthesized and characterized. 1 crystallizes in the orthorhombic system, space groups Pbcn, a=1.436 3(1) nm, b=1.477 2(1) nm, c=1.543 5(1) nm, V=3.274 7(4) nm3, Z=8, In 1, Hbtc2- as a four-connector bridges Cu(Ⅱ) node, and bmix ligand as a strut modifies its network structure. Eventually, the complex 1 displays a 3D (4,5)-connected net topology with a Schl?fli symbol of (42·5·62·8)(42·53·63·7·8). In addition，the thermal and catalytic degradation of methyl orange in photo Fenton like process associated with complex 1 also were investigated. CCDC: 791521. |
