Abstract Three novel tetranuclear copper(II) complexes namely [Cu 4 (L 1 ) 4 ]∙2(dmf) ( 1 ), [Cu 4 (L 1 ) 4 ] ( 2 ) and [Cu 4 (L 2 ) 2 (HL 2 ) 2 (H 2 O) 2 ]∙2(ClO 4 )·6(H 2 O) ( 3 ) (H 2 L 1 , ( E )−2-((1-hydroxybutan-2-ylimino)methyl)phenol; H 2 L 2 , (E)−2-((1-hydroxybutan-2-ylimino)methyl)−6-methoxyphenol)) were synthesized from the self-assembly of copper(II) perchlorate and the tridentate Schiff
摘要 三种新型四核铜(II)配合物即[Cu 4 (L 1 ) 4 ]∙2(dmf) ( 1 )、[Cu 4 (L 1 ) 4 ] ( 2 )和[Cu 4 (L 2 ) 2 ( HL 2 ) 2 (H 2 O) 2 ]∙2(ClO 4 )·6(H 2 O) ( 3 ) (H 2 L 1 , ( E )-2-((1-hydroxybutan-2-ylimino)methyl )苯酚; H 2 L 2 , (E)-2-((1-hydroxybutan-2-ylimino)methyl)-6-methoxyphenol)) 由高氯酸铜 (II) 和三齿席夫碱自组装合成配体。结构测定表明,配合物1在空间群C2/c的单斜晶系中结晶,而配合物2和3均在空间群P-1的三斜晶系中结晶。配合物 1 和 2 具有共享面的双立方核,而配合物 3 具有双开立方核结构。立方核中的铜 (II) 离子呈扭曲的方形平面几何形状,弱
