Abstract

In the title Pb(II) coordination polymer, [Pb(C(16)H(10)O(4))(C(14)H(8)N(4))(C(3)H(7)NO)](n), each Pb(II) atom is eight-coordinated by two chelating N atoms from one pyrazino[2,3-f][1,10]phenanthroline (L) ligand, one dimethylformamide (DMF) O atom and five carboxylate O atoms from three different 4,4'-ethylenedibenzoate (eedb) ligands. The eedb dianions bridge neighbouring Pb(II) centres through four typical Pb-O bonds and one longer Pb-O interaction to form a two-dimensional structure. The C atoms from the L and eedb ligands form C-H...O hydrogen bonds with the O atoms of eedb and DMF ligands, which further stabilize the structure. The title compound is the first Pb(II) coordination polymer incorporating the L ligand.
