| Synthesis, Crystal Structure and Photoluminescence of Zinc(Ⅱ) Complexes with a D-π-A Pyridine Ligand | |
| 摘要: 一种新型的D-π-A型吡啶配体L(L=反式-4-[4′-(N-甲基-N-羟乙基)胺]乙烯基吡啶) 与卤化锌反应，合成了3种配合物即ZnCl2L2 (1)，ZnBr2L2 (2)和ZnI2L2 (3)。其中配合物1和2通过X-射线单晶衍射的表征，分析结果表明这2种配合物中的锌原子都是四配位的，分别与配体中的2个氮原子和2个卤离子配位，而且锌原子形成的是畸变的四面体构型。在晶体中存在着许多弱作用力，包括氢键，π-π堆积等，这些都将影响他们的光致发光的性质。 | |

| Abstract: A series of novel zinc complexes (1, 2 and 3) are obtained by reaction of the ligand L (L=trans-4-[4′-(N-methyl-N-hydroxyethyl)amimo]vinylpyridine) with ZnX2 (X=Cl, Br, I). The crystal structures of complex ZnCl2L2 (1) and ZnBr2L2 (2) have been characterized by single crystal X-ray diffraction analysis. The results of the crystal structure determination show that the Zinc(Ⅱ) atom in these complexes are tetrahedrally coordinated by two nitrogen atoms from the ligands and two halide ions. The weak interactions including hydrogen bonds and π-π stacking play significant roles for their packing in crystal, which will influence on their photoluminescent properties.
