The new terphenyl pincer precursor 3, 3 ''-di-tert-butyl-1,1':3',1 ''-terphenyl-2,2 ''-diol (1) is examined for its ability to support early transition metals as a trianionic ligand. Metalation proceeds smoothly at -35 degrees C with Mo(NMe2)(4) to provide the Mo(IV), d(2) amido-amine complex [3, 3 ''-di-tert-butyl-2, 2 ''-di(hydroxy-KO)-1, 1':3',1 ''-terphenyl-2'-yl-KC2](N-methylmethanaminato)bis(N-methylmethanamine)molybdenum(IV), abbreviated as [BuOCO]Mo(NMe2)(NHMe2)(2), (2).
