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)] center dot H2O}(n) (1), {[Nd(BDOA)(1.5)(H2O)] center dot 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 P2(1)/c, they are isostructural and exhibit the same 3(21).4(57).5(13) topological network constructed from different coordination modes of two BDOA ligands, whereas isostructural 3 and 4 crystallizes in the triclinic system, space group P (1) over bar, it holds 3(9).4(20).5(7) 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. (c) 2007 Published by Elsevier B.V.
