Abstract

In the title PbII complex, [Pb2(C2Cl3O2)2(NO3)2(C12H8N2)2]n, the 1,10-phenanthroline ligand is chelating, the nitrate anion chelates one PbII ion and simultaneously bridges a neighbouring PbII ion via the third O atom, and the trichloroacetate anion is bidentate, bridging two PbII ions. The coordination geometry is based on a pentagonal–bipramidal geometry defined by an N2O5 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.
