Syntheses, structures and properties of seven isomorphous 1D Ln(3+) complexes Ln(BTA)(HCOO)(H2O)(3) (H(2)BTA = bis(tetrazoly)amine, Ln = Pr, Gd, Eu, Tb, Dy, Er, Yb) and two 3D Ln(3+) complexes Ln(HCOO)(3) (Ln = Pr, Nd)

Seven isomorphous 1D chain Ln(3+) 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 Ln(3+) complexes Ln(HCOO)(3) (Ln = Pr (8) and Nd (9)) have been synthesized and characterized by single crystal X-ray diffraction analysis. Although the Ln(3+) ions in 1-7 have different radius, the trivalent lanthanide ions in 1-7 show the same coordinated environment. The well-defined single crystal structures of 8 and 9 are first samples for formate-bridged Ln(3+) metallic complexes. The luminescent properties of solid samples of 2-5 at room temperature and the magnetic property of 2 have been also reported and discussed in this paper.
