摘要：

X-ray crystallography reveals four isostructural lanthanide polymeric solids, [Ln(2)(atp)(3)(H2O)(2)]center dot dmf center dot 4H(2)O (atp = 2-aminoterephthalate; dmf = N,N'-dimethylformamide; Ln = La (1), Ce*(2), Pr (3) and Nd (4), respectively) that are-obtained from the solvothermal synthesis which are crystallized in an interesting 3D polymeric framework with a (4,4,6)-linked {4(2). 8(4){4(4).6(2)}(2){4(8). 10(6) 8}(2) fsy net topology. Upon excitation at 350 nm, they all show the solid state ligand-centered luminescences but both 2 and 3 also exhibit the weak lanthanidebased characteristic emissions in the visible region at room temperature. The cyclic voltammetric investigation indicates that 2 exhibits appreciable electrochemical activity for formaldehyde. (C) 2015 Elsevier B.V. All rights reserved.
