Abstract

Treatment of tris(4-benzyl-1,2,3-triazolyl)methanol (Htbtm) with Cu^IBr in refluxed CH₂Cl₂ under aerobic conditions afforded the hexanuclear Cu^II complexes with the formula Cu₆(µ₃-O⋯H⋯O-µ₃)(µ-tbtm-к³-O,N³,N³′)₃(µ-Br)₆. The crystal structure reveals two Cu₃(µ-Br)₃(µ₃-O) units linked by three deprotonated tbtm ligands and a proton. Magnetic studies of the hexanuclear Cu^II cluster show a strong overall antiferromagnetic behavior with a dominant coupling interaction between Cu^II⋯Cu^II ions of different Cu₃(µBr)₃(µ₃-O) units.
