以较好的产率合成了三个三脚架结构的三（2-吡啶基甲基）胺（tpa）配体：[6-（羟甲基）-2-吡啶基甲基]双（2-吡啶基甲基）胺（HL 1）、双[6-（羟甲基）-2-吡啶基甲基]2-吡啶基甲基胺（H 2 L 2）、三[6-（羟甲基）-2-吡啶基甲基]胺（H 3 L 3）。从这些配体出发，合成了铜（II）配位配合物[Cu（HL 1）Cl]Cl 1，[Cu（H 2 L 2）Cl]X（X = Cl 2或对甲苯磺酸根3），[Cu（L2 BF 2）][BF 4] 4，一种新型大环阴离子与tpa核的配合物，[Cu（H3L3）Br0.43Cl0.57]2[Cu（Br0.43Cl0.57）2（Br0.97Cl0.03）2] 5与组成上无序的溴和氯共配体，合成了[Cu（H3 L3）Br]Br 6和不常见的三聚体[Cu 3 {H3（L3）2}Br][BF 4] 2 7，测定了它们的光谱、氧化还原性质和晶体结构。
Three potentially tripodal, tris(2-pyridylmethyl)amine (tpa) ligands with hydroxymethyl substituents, [6-(hydroxymethyl)-2-pyridylmethyl]bis(2-pyridylmethyl)amine (HL1), bis[6-(hydroxymethyl)-2-pyridylmethyl]2-(pyridylmethyl)amine (H2L2), tris[6-(hydroxymethyl)-2-pyridylmethyl]amine (H3L3), have been prepared in good yields. From these ligands, the copper(II) co-ordination complexes [Cu(HL1)Cl]Cl 1, [Cu(H2L2)Cl]X (X = Cl 2 or p-toluenesulfonate 3), [Cu(L2BF2)][BF4] 4 a complex of a novel macrocyclic anion with a tpa core, [Cu(H3L3)Br0.43Cl0.57]2[Cu(Br0.43Cl0.57)2(Br0.97Cl0.03)2] 5 with compositionally disordered bromo and chloro co-ligands, [Cu(H3L3)Br]Br 6 and the unusual trimer [Cu3{H3(L3)2}Br][BF4]27 have been synthesized and their spectroscopic and redox properties and crystal structures obtained.
