Abstract
Combined mass spectrometric and electron diffraction study of the overheate d vapor over calcium dipivaloylmethanate was performed It was established t hat one molecular form, Ca(DPM)(2), predominates in the vapor at 420-460 de grees C. The r(a), r(g), and r(alpha) parameters of the Ca(DPM)(2), molecul e were determined, and the symmetry of the molecule was found to be D-2d.
