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

Abstract

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(OBu t ) 3} 2(MeCN)] or formation of four intramolecular, interligand O–H ⋯ O hydrogen bonds in the case of [Mn{SSi(OBu t ) 3} 2(MeOH) 4] serve to stabilize the complexes.
