摘要：
A straightforward synthetic method to prepare mononuclear croconato-containing iron (III) complexes, (A)3[Fe(C5O5)3] [A = tetrabutylammonium = n-Bu4N+ (1) and tetraphenylphosphonium = PPh4+ (2); C5O52- = croconate = dianion of 4, 5-dihydroxycyclopent-4-ene- 1, 2, 3-trione] along with their crystal structures and magnetic properties, are reported. The Fe(III) atom adopts a pseudo-octahedral geometry while magnetic susceptibility measurements, in the 2-300 K temperature range, show the occurrence of a high spin state (S = 5/2) in both complexes.
