 Abstract: TlCu2O2, a mixed-valence spin-chain cuprate, was synthesized in a piston cylinder system starting from thallium sesquioxide Tl2O3, cuprous oxide Cu2O and copper powder. The main structural characteristics are edge-sharing (CuO2)(n) zigzag chains, which are linked in the perpendicular crystallographic direction by Cu+ to form a three-dimensional network. Data from magnetic susceptibility and specific heat measurements show features typical for low-dimensional magnetic exchange interactions. The long-range antiferromagnetic ordering is observed at T-N = 19.7 K. No weak ferromagnetic component can be detected, suggesting a plain Neel-type spin-ordered structure.
