摘要：

The single crystal X-ray data of a mixed anions complex of Pb-II with 1,10-Phenantroline, [Pb(phen)(O2CCH3)-(O2NO)], shows the complex to be polymeric as a result of acetate ligand bridging. The Pb atom has an asymmetrical eightfold coordination of two nitrogen atoms of the 1,10-phenanthroline ligand and six oxygen atoms of the nitrate and acetate anions. The arrangement of the 1,10-phenantroline ligand, acetate and nitrate anions suggest a gap in the coordination around the Pb-II ion, occupied possibly by a stereoactive lone pair of electrons on lead(II) where the coordination around the lead atoms is hemidirected. There is a pi-pi stacking interaction between the parallel aromatic rings of an adjacent chain in the compound which might help to increase the 'gap' in the coordination around the Pb-II ion.
