Abstract
|
|
|
|
The charge-transfer complexes formed between some different metal 2,4-pentadionato complexes and p-electron acceptor (picric acid, PA) are synthesized and characterized. Spectral characteristics and stability of the complexes are investigated and discussed in terms of donor molecular structure and p-acceptor at room temperature in chloroform. The results indicate the formation of 1:1 charge-transfer complexes with a general formula, [M(acac)n(PA)] where (M=Cu(II), Ni(II), Mn(II), Fe(III), Co(III), Cr(III), Al(III) and Zr(IV); n=2, 3 or 4). The charge-transfer absorptions, elemental analysis, infrared spectra and gravimetric studies were recorded and discussed.
