Abstract
Treatment of tris(4-benzyl-1,2,3-triazolyl)methanol (Htbtm) with CuIBr in refluxed CH2Cl2 under aerobic conditions afforded the hexanuclear CuII 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 CuII cluster show a strong overall antiferromagnetic behavior with a dominant coupling interaction between CuII⋯CuII ions of different Cu3(µBr)3(µ3-O) units.
