本文合成了2个以席夫碱2-[(E)-(3-氯苯胺基)甲基]-6-溴4-氯苯酚(HL)为配体的单核配合物CuL2(1)和ZnL2(2)。X-射线衍射分析表明两个配合物分别是一维与二维的高聚物形式的超分子体系。其中配合物1的几何构型是平面正方形,依靠分子间的C-H…O与C-H…Br氢键作用联结成二维网状结构。配合物2展现的是畸变的四面体构型,分子间的C-H…O的弱的相互作用将其联结成一维链状结构。两个配合物中,氢键在高聚物链的形成中和配合物结构的稳定中起着很重要的作用。
In this paper, two mononuclear complexes CuL2 (1) and (2) were synthesized with Schiff base 2 - [(E) - (3-chloroanilino) methyl] -6-bromo- ZnL2 (2). X-ray diffraction analysis showed that the two complexes are one-dimensional and two-dimensional polymeric form of supramolecular system. The geometrical configuration of complex 1 is planar square and relies on the hydrogen bond between C-H ... O and C-H ... Br molecules to form a two-dimensional network structure. Complex 2 shows a distorted tetrahedral configuration, and the weak interaction of C-H ... O molecules between molecules links it into a one-dimensional chain structure. Among the two complexes, hydrogen bonding plays an important role in the formation of polymer chains and the stability of the complexes.
