摘要: 本文合成了2个新的席夫碱,N,N'-二(5-氯水杨基)-1,3-二氨基戊烷(H2CAP)和N,N'-二(5-溴水杨基)-1,3-二氨基戊烷(H2BAP),以及它们的铜(Ⅱ)配合物,[Cu(CAP)](1),[Cu(BAP)](2)和[Cu(CAP)0.5(BAP)0.5](3),并通过元素分析、红外和电子光谱表征了它们的结构。对于配合物,还利用单晶X-射线衍射进行了结构测试。在每个配合物中,铜原子都采取四面体畸变的平面四边形配位构型。通过将配合物1和2结合在一起形成了聚集体3。在该聚集体中存在有趣的氯和溴取代基交替排列现象。 |

Abstract: Two new Schiff bases, N,N'-bis(5-chlorosalicylidene)-1,3-diaminopentane (H2CAP) and N,N'-bis(5-bromosalicylidene)-1,3-diaminopentane (H2BAP), and their copper(Ⅱ) complexes, [Cu(CAP)] (1), [Cu(BAP)] (2) and [Cu(CAP)0.5(BAP)0.5] (3), have been prepared and structurally characterized by elemental analysis, IRand electronic spectroscopy. The complexes have also been characterized by single-crystal X-ray diffraction studies. The Cu atom in each of the complexes is in a tetrahedrally distorted square planar coordination. By combination of complex 1 and 2, a new aggregation 3 was formed. There are interesting alternate arrangement of Cl and Br substituent groups in the crystal packing of the aggregation.
