Molybdenum complexes of poly[(methylthio)methyl]borates

Add time:07/13/2019    Source:sciencedirect.com

Organometallic molybdenum compounds bearing poly[(methylthio)methyl]borates, [(η3-C3H5)Mo(CO)2(κ3-PhTt)] and [Bu4N][{(η3-C3H5)Mo(CO)2Cl}2(κ2:κ2-RTt)], where PhTt = phenyltris[(methylthio)methyl]borate and RTt = tetrakis[(methylthio)methyl]borate, have been obtained by ligand exchange reaction from [(η3-C3H5)Mo(CO)2(NCMe)2Cl] and appropriate borate. The PhTt ligand provides tridentate face-capping coordination to the central metal while the RTt acts as a bridging ligand and connects two [(η3-C3H5)Mo(CO)2Cl] monomeric units by unusual κ2:κ2-coordination mode. Both compounds were fully characterized by spectroscopic methods and X-ray crystallography.
