An unsymmetrically sandwiched bis(O3S2-macrocycle) lead(ii) complex via an endo/exo-coordination mode

Abstract

An unsymmetrically sandwiched complex was isolated from the reaction of O₃S₂-macrocycle with lead(II) perchlorate. The lead(II) centre is bound to one macrocycle in an endocyclic (face) mode and the other in an exocyclic (edge) mode, resulting in a di-capped trigonal prismatic geometry. The edge-to-face sandwich complex might be associated with the hemispherical lead(II) coordination.
