| Abstract: | The overheated vapor of yttrium tris-dipivaloyl methanate was studied by combined electron diffractometry and mass spectrometry.
It was established that at 760 K the vapor of Y(DPM)3 contains the Y(DPM)2 molecular form. The ra, rg, and ra parameters of Y(DPM)2 were determined, and it was found that the chelate system of Y(DPM)2 has a planar structure. Possible reasons for differences in the intemuclear distances of the Y(DPM)2 and Y(DPM)3 molecular forms are discussed.
