Four three-dimensional lanthanide coordination polymer constructed from benzene-1,4-dioxydiacetic acid

Four crystalline lanthanide(III) three-dimensional (3D) coordination polymers {[La(BDOA)1.5(H2O)] · H2O}n (1), {[Nd(BDOA)1.5(H2O)] · H2O}n (2), [Tm(BDOA)1.5(H2O)]n (3), [Yb(BDOA)1.5(H2O)]n (4) were obtained under hydrothermal conditions and characterized by elemental analysis, IR, as well as single-crystal X-ray diffraction. Compounds 1 and 2 crystallize in the monoclinic system, space group P 21/c , they are isostructural and exhibit the same 321.457.513 topological network constructed from different coordination modes of two BDOA ligands, whereas isostructural 3 and 4 crystallizes in the triclinic system, space group View the MathML sourceP1¯, it holds 39.420.57 topological architecture based on another two different coordination modes BDOA ligands. Moreover, a computational method is applied to evaluate the potential porosity of complex 1.
