The manganese(I) tricarbonyl complexes (BmR)Mn(CO)3 (R = Me, Bz, But, p-Tol) and (PhBmMe)Mn(CO)3, the first bis(mercaptoimidazolyl)borate derivatives for this metal, have been readily prepared and fully characterized. In particular, the presence of three-center-two-electron Mn ⋯ H-B interactions in these species, both in solution and in the solid state, has been investigated using a combination of IR and NMR spectroscopies and, in the case of the methyl-, tert-butyl- and para-tolyl-substituted derivatives, by X-ray crystallography. To complement these synthetic and structural studies, the tris(mercaptoimidazolyl)borate complexes (TmMe)Mn(CO)3 (R = Me, Bz, But, p-Tol) and (PhTmMe)Mn(CO)3, as well as the related pyrazolylbis(mercaptoimidazolyl)borate (pzBraMe)Mn(CO)3, have also been synthesized and characterized by a combination of analytical and spectroscopic techniques.
