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]
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 [MnSSi(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 [MnSSi(OBu')(3)}(2)(MeOH)(4)] serve to stabilize the complexes.
