Seven isomorphous 1D chain Ln3+complexes Ln(BTA)(HCOO)(H2O)3(Ln = Pr (1), Gd (2), Eu (3), Tb (4) Dy (5), Er (6) and Yb (7)), and two formate coordinating and bridging 3D Ln3+complexes Ln(HCOO)3(Ln = Pr (8) and Nd (9)) have been synthesized and characterized by single crystal X-ray diffraction analysis. Although the Ln3+ions in 1–7have different radius, the trivalent lanthanide ions in 1–7show the same coordinated environment. The well-defined single crystal structures of 8and 9are first samples for formate-bridged Ln3+metallic complexes. The luminescent properties of solid samples of 2–5at room temperature and the magnetic property of 2have been also reported and discussed in this paper. [ABSTRACT FROM AUTHOR]
