Five isostructural copper(II)-lanthanide(III) heterometallic coordination polymers (CPs), {[Cu(2)Ln(TDA)(2)Cl(H2O)(4)]center dot 2H(2)O}(n) [Ln = Gd (Cu-Gd), Tb (Cu-Tb), Dy (Cu-Dy), Ho (Cu-Ho) and Er (Cu-Er)] (H(3)TDA = 1H-1,2,3-triazole-4,5-dicarboxylic acid), have been synthesized under solvothermal conditions and structurally characterized in detail. In these CPs, two neighboring Cu(II) ions are connected via one mu(2)-Cl to form [Cu2Cl](3+) units, which are further linked into a copper chain through bridging TDA(3-). The neighboring copper chains are further connected by lanthanide to form a two-dimensional structure with sql topology. The magnetic properties of the five isostructural heterometallic CPs have been studied as well.
