The X-ray diffraction studies reveal 2 and 3 contain five-coordinated Cu(II) atom which is surrounded by two nitrogen and three oxygen atoms. The coordination geometry of complexes were examined using the Addison's model. The results show that complex 2 has distorted trigonal bipyramidal geometry, but complex 3 has distorted square pyramidal geometry. Also, the synthesized copper complexes can be regarded
摘要 源自 2,4,6-trioxohexahydroprimidine-5-carbaldehyde 的 Schiff 碱可以作为螯合配体。5-[(2,6-diisopropylphenylamino)-methylene]pyrimidine-2,4,6-trione (LB1) 和 1,3-dimethyl-5-[(2-phenoxyphenylamino)-methylene]pyrimidine-2,4,6 -trione (LB2) 被用作合成新型单核五配位铜 (II) 配合物的配体。通过FT-IR和NMR检测配体的光谱性质。LB2 的分子结构由 X 射线衍射确定,该衍射在正交 Pca21 空间群中结晶。Cu(LB1)2 (2) 和Cu(LB2)2 (3) 的配合物通过元素分析、FT-IR 和X 射线衍射表征。X 射线衍射研究表明 2 和 3 含有五个配位的 Cu(II) 原子
