Synthesis and characterization of polynuclear copper(II) complexes with pyridylbis(phenol) ligands

Inorg Chem. 2009 May 4;48(9):4083-8. doi: 10.1021/ic9000768.

Abstract

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)](ClO(4))(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).
