Description

Crystals of benzoyl acetonates of Mn (II), Cd (II) and Fe (III) have been prepared. Their structures have been determined by X-ray powder diffraction. Thermogravimetric analysis (TGA) of these benzoyl acetonate indicate that they are stable up to 90 deg. C,220 deg. C, 65 deg. C, and 190 deg. C respectively. It is found that the thermal stability of the transition meals chelates follows the order Cd/sup 2+/ < Mn/sup 2+/ < Fe/sup 3+/<Ni/sup 2+/. The chelate of Cd(II) (last member of the second transition series) has the lowest temperature of decomposition of all the compounds studied. (author)
