| Abstract: | A lead(II) complex with 1,10-phenanthroline (phen) containing two different anions has been synthesized using a direct synthetic method and characterized by IR and CHN elemental analysis. The structure of Pb(phen)(2OCCH3)(NCS)]2 was confirmed by X-ray crystallography. The single crystal X-ray data of this compound shows the complex to be dimeric as a result of acetate ligand bridging. The Pb atom has an unsymmetrical six-coordinate geometry, being coordinated by three nitrogen atoms of 1,10-phenanhroline and the thiocyanate ligand and three oxygen atoms of the acetate ligand. The arrangement of the 1,10-phenanhroline, acetate and thiocyanate ligands exhibits a coordination gap around the Pb(II) ion, occupied possibly by a stereoactive lone pair of electrons on lead(II), with the coordination around lead atoms being hemidirected. There is a π–π stacking interaction between the parallel aromatic rings that may help to increase the ‘gap’ in the coordination geometry around the Pb(II) ion. |
