The preparation, characterization, and electronic structure of homoleptic complexes of molybdenum and tungsten bridged by bis(alkylamido)phenylboranes, M-2[RN-B-Ph-NR](3) (M = Mo, R = Et (1), Pr-i (2); M = W, R = Et (3), Pr-i (4)), are described. These triple metal-metal bond species (i) exhibit a nearly eclipsed ligand geometry and (ii) possess the shortest metal-metal bonds of neutral dimolybdenum and ditungsten M2X6 complexes observed to date (d(Mo-Mo) = 2.1612(6) Angstrom (1); d(W-W) = 2.2351(7) Angstrom (4)).
