摘要: 在路易斯酸ZnCl2或MnSO4·7H2O作用下,通过1-甲基-1-氢-咪唑-4,5-二甲腈与NaN3水热原位合成了2个四唑配合物:{[Zn2(midt)(Hmidt)](N3)·H2O}n (1)和[Mn(midt)2·(H2O)2]·H2O (2)(midt=1-甲基-1-氢-咪唑-4,5-二四唑)。X射线单晶衍射表明尽管配合物1和2均结晶于同样的P1 空间群,但他们有完全不同的结构。配合物1为一个有趣的二维聚合物结构,含有两个不同配位环境的锌原子和多种配位模式的midt配体,而配合物2为一个三维超分子结构,包含一个有趣的水分子链结构。固态下1和2分别在353和382 nm处显示出较强的蓝色荧光。 |

Abstract: Two tetrazole complexes, {[Zn2(midt)(Hmidt)](N3)·H2O}n (1) and [Mn(midt)2·(H2O)2]·H2O (2) (midt=1-methyl-1H-imidazole-4,5-ditetrazole), were synthesized via hydrothermal reaction of 1-methyl-1H-imidazole-4,5-dicarbonitrile (midn) and NaN3 in the presence of ZnCl2 or MnSO4·7H2O as Lewis acid. X-ray single crystal diffraction analyses indicate that both 1 and 2 have different crystal structures although they crystallize in the same P1 space group. Complex 1 demonstrates an interesting two dimensional polymeric structure which contains two crystalgraphically different Zn(Ⅱ) ions and midt ligands with diversified coordination modes, while 2 shows a 3D supramolecular structure involving a water clusters chain. Moreover, 1 and 2 display strong blue emission at 353 and 382 nm at room temperature. |
