Structural Diversity in Divalent Group 14 Triflate Complexes Involving Endocyclic Thia-Macrocyclic Coordination.

ABSTRACT: A highly unusual series of M(II) (M = Ge, Sn, Pb) complexes with endocyclic thioether macrocyclic coordination and with coordination numbers ranging from three to nine have been prepared by the reaction of [9]aneS₃ (1,4,7-trithiacyclononane), [12]aneS₄ (1,4,7,10-tetrathiacyclododecane), or [24]aneS₈ (1,4,7,10,13,16,19,22-octathiacyclotetracosane) with M(OTf)₂ (M = Sn and Pb; OTf = CF₃SO₃^-) or with GeCl₂·dioxane and 2 mol equiv of TMSOTf (Me₃SiO₃SCF₃) in a mixture of anhydrous CH₂Cl₂ and MeCN. The isolated bulk products are characterized by ¹H, ¹³C{¹H}, ¹⁹F{¹H}, and ¹¹⁹Sn{¹H
