Abstract
The overheated vapor of yttrium tris-dipivaloyl methanate was studied by combined electron diffractometry and mass spectrometry. It was esta blished that at 760 K the vapor of Y(DPM)(3) contains the Y(DPM)(2) mo lecular form. The r(a), r(g), and r(a) parameters of Y(DPM)(2) were de termined, and it was found that the chelate system of Y(DPM)(2) has a planar structure. Possible reasons for differences in the internuclear distances of the Y(DPM)(2) and Y(DPM)(3) molecular forms are discusse d.
