Abstract

In the title Pb II complex, [Pb 2(C 2Cl 3O 2) 2(NO 3) 2(C 12H 8N 2) 2] n , the 1,10-phenanthroline ligand is chelating, the nitrate anion chelates one Pb II ion and simultaneously bridges a neighbouring Pb II ion via the third O atom, and the trichloro-acetate anion is bidentate, bridging two Pb II ions. The coordination geometry is based on a pentagonal-bipramidal geometry defined by an N 2O 5 donor set with no obvious stereochemical role for the lead-bound lone pair of electrons. The coordination polymer has a zigzag topology along [010] and comprises alternating eight-membered {PbONO} 2 and {PbOCO} 2 rings.
