A series of novel three-dimensional (3D) Ln(III)-Cu(I) heterometallic tetrazole-based coordination polymers, namely, [LoCu(3-tzba)(2)(H2O)(4)](n) [Ln = Ho (1); Nd (2); Sm (3); Pr (4); 3-tzba = 3-(1H-tetrazol-5-yl)benzoate], were successfully synthesized through in situ [2 3] cycloaddition reaction under hydrothermal conditions. Compounds 1-4 are isomorphous 3D coordination frameworks with 1D anionic chains [Ln(3-tzba)(2)(H2O)(4)](-) linking the adjacent Cu(I) ions possessing an sql type net with Schlafli symbol (4(4)). To our best knowledge, they are the first lanthanide-transition heterometal-organic coordination polymers obtained through in situ tetrazole synthesis. In addition, the thermal stability and magnetic property of 1 were also investigated.
