New chiral heteroleptic germanium(ii) and tin(ii) metallylenes were obtained using 1-(para-tolylsulfinyl)-3-tosyl-5-tert-butyl-benzene as a non-symmetric O,C,O-chelating pincer ligand. Crystallographic analysis and DFT calculations indicate that the non-symmetric sulfinyl-sulfonyl pincer ligand acts as an O,C,O-coordinating pincer-type-ligand with predominant sulfinyl intramolecular S[double bond, length as m-dash]O coordination to germanium(ii) and tin(ii) centers.
新型手性杂核锗（II）和锡（II）茂金属配合物是使用 1-（对甲苯亚磺酰基）-3-对甲苯磺酰基-5-叔丁基苯作为非对称 O，C，O 螯合型 pincer 配体得到的。晶体学分析和 DFT 计算表明，非对称亚磺酰基-砜基 pincer 配体作为 O，C，O 配位的 pincer 型配体，主要通过亚磺酰基分子内 S[双键，长度为 m-dash]O 配位与锗（II）和锡（II）中心配位。
