Abstract
Abstract The molecular structure of tris(dipivaloylmethanato)lanthanum(III), La(dpm) 3 , was determined by gas-phase electron diffraction combined with mass spectrometry (GED/MS) at the temperature 207(5)°C. According to the mass spectrum the vapour consisted of only La(dpm) 3 molecules up to the temperature at least 250°C. The molecule was found to have D 3 symmetry and the following bond lengths in the chelate ring: r α (La–O)=2.371(6) A, r α (O–C)=1.278(5) A, r α (C–C r )=1.396(7) A.
