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]
چکیده انگلیسی

First manganese(II) trialkoxysilanethiolates have been prepared using tri-tert-butoxysilanethiol as 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(OBut)3}2(MeCN)] or formation of four intramolecular, interligand O–H ⋯ O hydrogen bonds in the case of [Mn{SSi(OBut)3}2(MeOH)4] serve to stabilize the complexes.

First two manganese(II) trialkoxysilanethiolates have been prepared and characterized. Both contain solvent as coligand. In [Mn{SSi(OBut)3}2(NCMe)], manganese is five-coordinate – silanethiolate ligand interacts with a metal simultaneously through sulfur and oxygen atoms and thus exhibits chelating character. Octahedral, methanol ligated complex (see figure) may serve as an example of a structure “reinforced” by a set of intramolecular and interligand O–H…O hydrogen bonds.Figure optionsDownload as PowerPoint slide
