摘要：

A one-dimensional linear coordination polymer {[Cu-3(mu(3)-OH)(2-pyao)(3)(bdc)]center dot 6(H2O)}(n) (1) composed of trinuclear [Cu-3(mu(3)-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 (H(2)bdc). Magnetic susceptibility measurements show strong antiferromagnetic interactions between Cu(II) centers within the trinuclear metallacrown core with J = -430 cm(-1).
