Abstract

The reaction of 2,6-pyridinedicarbaldehyde with 2,6-bis[(2-aminoethyl)thiomethyl)]pyridine in the presence of Pb(O2CMe)2 yields the mononuclear lead(II) complex of a [1 + 1] 18-membered, potentially hexadentate, N4S2 imine macrocycle, the crystal and molecular structure of which has been determined [space group Pc, a = 8.358(3), b = 15.158(5), c = 10.127(4) angstrom, beta = 99.87(3)-degrees]. This structure represents a rare example of a structurally characterised lead(II) complex with a macrocyclic ligand containing both nitrogen and sulfur donor atoms.
