Three new pyridylbis(phenol) ligands with imine (H(2)L(imine)), amine (H(2)L(amine)), or amide (H(4)L(amide)) linkages, along with their copper complexes, were synthesized and characterized. Treatment of H(2)L(imine) with copper(II) in the presence of base produced mononuclear copper complex [Cu(L(imine))(MeOH)] (1), while the same procedure with H(2)L(amine) produced trinuclear Cu(3)(L(amine))(2)(CH(3)CN)(2)(2) (2). The more rigid H(4)L(amide) forms tetranuclear [Cu(4)(L(amide))(2)(H(2)O)(4)] (3), which upon recrystallization yielded crystals of hexanuclear [Cu(6)(HL(amide))(4)(H(2)O)(2)] (4).
合成并表征了三种带有亚胺（H₂L(imine)）、胺（H₂L(amine)）或酰胺（H₄L(amide)）键的新型吡啶基双酚配体及其铜配合物。在碱存在下，用铜（II）处理H₂L(imine)生成单核铜配合物[Cu(L(imine))(MeOH)]（1），而用H₂L(amine)进行相同操作则生成三核Cu₃(L(amine))₂(CH₃CN)₂₂（2）。刚性更强的H₄L(amide)形成四核[Cu₄(L(amide))₂(H₂O)₄]（3），重结晶后得到六核[Cu₆(HL(amide))₄(H₂O)₂]（4）的晶体。
