Abstract

A one-dimensional linear coordination polymer {[Cu3(μ3-OH)(2-pyao)3(bdc)]·6(H2O)}n (1) composed of trinuclear [Cu3(μ3-OH)(2-pyao)3]2+ metallacrown cores bridged by bis-carboxylato linkers has been obtained by treatment of copper(II) fluoride with pyridine-2-aldoxime (2-pyaoH) ligand and benzene-1,4- dicarboxylic acid (H2bdc). Magnetic susceptibility measurements show strong antiferromagnetic interactions between Cu(II) centers within the trinuclear metallacrown core with J = −430 cm−1.
