• Complexes of trimethylplatinum(<scp>IV</scp>) halides with dithio- and diselenoethers, dimethyl disulphide, and dimethyl diselenide

  DOI：10.1039/dt9800001169

  日期：——

  Trimethylplatinum(IV) halides react with MeE(CH2)nEMe, E = S or Se, n= 2 or 3, to give mononuclear species [PtXMe3MeE(CH2)n EMe}], X = Cl, Br or I. Under similar conditions the ligands L–L = MeECH2EMe, MeECH(Me)EMe, and MeEEMe, E = S or Se, give dinuclear complexes [(PtXMe3)2(L–L)] in which the S or Se donor ligand bridges the metal atoms. Structural asignments are based on 1H n.m.r. solution studies

  三甲基铂（IV）卤化物与MeE（CH 2）n EMe，E = S或Se，n = 2或3反应生成单核种[PtXMe 3 MeE（CH 2）n EMe}]，X = Cl，Br或I。在类似条件下，配体L–L = MeECH 2 EMe，MeECH（Me）EMe和MeEEMe，E = S或Se，生成双核络合物[（PtXMe 3）2（L–L）]，其中S或Se供体配体桥接金属原子。结构分配基于1 H nmr解决方案研究。
