Selective 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 (CCCIm) [SnSO(SMe)][An] (), (dmmpH)[MnSnSe(SeMe)] (), and (C CIm)[HgTe(TeMe)] (, ). The methylation was confirmed by Raman spectroscopy, and the optical absorption properties of the methylated compounds were determined and compared to purely inorganic analogs.
在与基于烷基咪唑鎓的离子液体进行离子热反应时，分子硫属化物金属酸盐阴离子的末端硫属化物配体的选择性甲基化产生了一系列有机官能化的硫属化物金属酸盐化合物。我们展示了(CCCIm)[SnSO(SMe)][An]（）、(dmmpH)[MnSnSe(SeMe)]（）和(C CIm)[HgTe(TeMe)]（，）的合成方法和晶体结构。通过拉曼光谱证实了甲基化，并测定了甲基化化合物的光吸收特性，并与纯无机类似物进行了比较。
