Synthesis, crystal structure and magnetic property of a new layered copper(II) complex with picolinic acid N-oxide built from Cu2O2 dimer units

Reaction of copper(II) chloride with picolinic acid N-oxide (HL) in acetone/THF mixed solvent afforded a novel layered compound, [Cu(L)Cl(H2O)]2, in which each pair of octahedrally coordinated copper(II) ions are bridged by two N-oxide groups to form a Cu2O2 dimeric unit, and such dimeric units are further interconnected via carboxylate groups to form a layer.
