  Reaction of methanol ligated manganese(II) silanethiolate with pyridine related ligands – Different structures of complexes with MnNO2S2 kernel

  摘要：

  The reaction of [Mn{SSi(OBut)(3)}(2)(MeOH)(4)] With pyridine and its three monosubstituted methyl derivatives leads to the formation of two distinct types of complexes, although both with the MnO2NS2 kernel. The first two compounds (with pyridine or 2-picoline) contain two silanethiolate ligands, heterocyclic base and two methanol molecules. In the second case (3- and 4-picoline) the role of O-donor and simultaneously S-donor ligand is fulfilled by tri-tert-butoxysilanethiolate rest which under favorable conditions can serve as a chelating agent.

  The first manganese trialkoxysilanethiolates: Formation, properties and structure of solvent ligated complexes – [Mn{SSi(OBut)3}2(MeCN)] and [Mn{SSi(OBut)3}2(MeOH)4]

  摘要：

  First manganese(H) trialkoxysilanethiolates have been prepared using tri-tert-butoxysilanethiol its the ligand Source and their structure determined by X-ray diffraction. Acetonitrile or methanol used as reaction solvents was found to enter Mn coordination sphere. Obtained heteroleptic silanethiolate complexes represent two distinct structural types. Either O,S-chelation by tri-tert-butoxysilanethiolate ligand and simultaneous electronic assistance provided by acetonitrile in [Mn{SSi(OBu')(3)}(2)(MeCN)] or formation of four intramolecular, interligand O-H center dot center dot center dot O hydrogen bonds in the case of [Mn{SSi(OBu')(3)}(2)(MeOH)(4)] serve to stabilize the complexes.

  3a represents another type of complex, where the same silanethiolate ligand is bonded to manganese only through a sulfur atom, and a methanol molecule is present within the metal coordination sphere. The structure type found in 3a is characterized by a penta-coordinated Mn centre, a MnN2OS2 kernel, and the presence of three different ligands was previously unknown among manganese compounds.

  摘要不稳定的双（三叔丁氧基硅烷硫醇基）四（甲醇）锰（II）[Mn SSi（OBut）3} 2（MeOH）4]（1）与螯合的杂环碱（联吡啶，菲咯啉和新cuproine）反应导致形成新的杂合锰（II）三叔丁氧基硅烷硫醇盐配合物，并表现出显着的稳定性。元素和光谱分析（IR，MS，UV-Vis）表明，在所有三种情况下，两个硅烷硫醇盐配体和一个杂环碱都附着在金属中心，从而与[Mn SSi（OBut）3} 2（N–N）形成配合物]化学计量，其中N = 2，2'-联吡啶（2），1,10-菲咯啉（3）和新卡普林（4）。作为从2的甲醇单晶重结晶的结果，形成了新的不稳定的络合物[Mn SSi（OBut）3} 2（phen）（MeOH）]（3a），并确定了它们的结构。两种络合物都是单金属的。2中的锰原子是六配位的，中心的MnN2O2S2核是三叔丁氧基硅烷硫醇盐配体的O，S螯合能力产生的。化合物3a代表另一
