| 摘要: 采用溶液法合成了2个含2-巯基吡啶-1-氧(mpo)的Au(Ⅰ)配合物:(ph3P)Au(mpo) (1)和[Au(mpo)2][Na(H2O)4]·H2O (2)。通过X-射线单晶衍射与元素分析等方法确定了其晶体结构。配合物1属单斜晶系,空间群为P21/c,而配合物2属正交晶系,空间群为Pnma。配合物1的结构为零维的(ph3P)Au(mpo),而配合物2的结构是Au(mpo)2单元与一维Na(H2O)4带以及游离水分子通过氢键连结而成的三维结构。荧光测试表明,化合物2在300 nm紫外光激发下可以发射较强的蓝光(423.5 nm)。 |

| Abstract: Two new Au(Ⅰ) complexes, namely, (ph3P)Au(mpo) (1) and [Au(mpo)2][Na(H2O)4]·H2O (2) have been synthesized via the reaction of (ph3P)AuCl with 2-mercaptopyridine-1-oxide sodium (Nampo) in dichloromethane (CH2Cl2) solution. Their crystal structures have been determined by elemental analysis and single-crystal X-ray diffraction studies. Complex 1 crystallizes in the monoclinic system, space group P21/c, and features isolated (ph3P)Au(mpo) molecules. Complex 2 crystallizes in the orthorhombic system, space group Pnma. The structure of complex 2 features three-dimensional (3D) network composed of Au(mpo)2 units, 1D Na(H2O)4 belt as well as isolated H2O molecules interlinked via weak hydrogen bonds. Complex 2 exhibits blue emission with λmax=423.5 nm by irradiation of UV light (λ=300 nm). CCDC: 932336, 1; 932337, 2. |
