The title complex, (17-benzyloxy-2,5,8,15,19-pentaoxatricyclo[18.4.0.09,14]tetracosa- 9,11,13,20,22,24-hexaene-κ6O)bis(nitrato-O,O')lead(II), [Pb(NO3)2(C26H28O6)], prepared from benzyl sym-dibenzo-16-crown-5 ether and Pb(NO3)2 in aqueous CHCl3/MeOH at room temperature, has decacoordinate geometry for the Pb2+ ion, with bonds to the five ring O atoms, the side-arm ether O atom and two O atoms of each of the two coordinated nitrate ions. The four Pb—O bond lengths for the nitrate ligands are considerably shorter than those for the crown ether.
