Abstract

Bis-(Isobutyrylketonate) complexes of II group metals have been prepared and their variable 1H-NMR spectra have been investigated. Chemical shifts values and other arguments led us to favor a pseudo-tetrahedral D2d idealized structure for all the complexes investigated but the free energy of activation for the enantiomerization (inversion at the metal tetrahedral atom) could not be determined due to the accidental isochrony of the isopropyl methyl groups in all the range of temperature investigated. © 1980.
