Abstract:

An iron(III) complex [FeIII(TpzMe2)(HpzMe2)Cl2](1) has been synthesized at a low temperature, which contains tripodal ligand, namely, the anionic hydrotris-3,5-dimethyl-pyrazolylborate(TpzMe2). A series of iron(III) catecholate complexes 2―5 has been obtained via the reaction of compound 1 with catecholate or substituted catecholates. These complexes were characterized by X-ray crystallographic analysis, mass spectrometry and elemental analysis, and the results show that TpzMe2 ligand has the beneficial effect on the stabilization of iron(III) catecholate complexes.

Key words: Iron complex; Hydrotris-3,5-dimethyl-pyrazolylborate; Catecholate
