N2 - An unexpected novel coordination mode of diazoalkanes has been verified via addition of 2-diazopropane to the metal-metal triple bond of bis[dicarbonyl(η5-pentamethylcyclopentadienyl)molybdenum] (MoMo). The dinuclear 1:1 addition product isolated in nearly quantitative yield is structurally characterized by a bent, 4-electron type η1:η2-diazoalkane ligand, with the terminal nitrogen atom symmetrically bridging the metal-metal "single bond" (d(MoMo) 305.0(2) pm; d(MoN(1)) 212.0(12) and 212.6(10) pm, respectively) and the second nitrogen atom being bonded to one molybdenum atom only (d(MoN(2)) 213.4(13) pm).
