Electron-Diffraction Study of Diborane and Deuterodiborane

The molecular structures of gaseous B2H6 and B2D6 were determined by the sector-microphotometer method of electron diffraction. Structural parameters and standard errors for B2H6 were rg(B–B) = 1.7750±0.0035 Å; rg(B–H)term = 1.1960+0.008, −0.006 Å; rg(B–H)bridge = 1.3393+0.002, −0.006 Å; and
