Ionic liquid cations as methylation agent for extremely weak chalcogenido metalate nucleophiles

Selective in situ methylation of terminal chalcogenide ligands of molecular chalcogenido metalate anions in ionothermal reactions with alkylimidazolium-based ionic liquids yields a series of organo-functionalized chalcogenido metalate compounds. We present the syntheses and crystal structures of (C(...

Sumario:Selective in situ methylation of terminal chalcogenide ligands of molecular chalcogenido metalate anions in ionothermal reactions with alkylimidazolium-based ionic liquids yields a series of organo-functionalized chalcogenido metalate compounds. We present the syntheses and crystal structures of (C(4)C(1)C(1)Im)(4+x)[Sn(10)S(16)O(4)(SMe)(4)][An](x) (1a–1f), (dmmpH)(6)[Mn(4)Sn(4)Se(13)(SeMe)(4)] (2), and (C(n)C(1)Im)(6)[Hg(6)Te(10)(TeMe)(2)] (3a, 3b). The methylation was confirmed by Raman spectroscopy, and the optical absorption properties of the methylated compounds were determined and compared to purely inorganic analogs.
