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(...

description 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.
