Abstract
A series of mono- and bi-nuclear iron(III) complexes with three bis(acylhydrazones)(acyl = pyridine-2-carbonyl, salicyloyl or 2-thenoyl) and the mono(2-thenoylhydrazone) of 2,6-diacetylpyridine have been prepared and characterized by IR and 57Fe Mössbauer spectroscopy. The X-ray crystal structure of dichloro[2,6-diacetylpyridine bis(salicyloylhydrazonato)(4–)]bis(ethanol)diiron(III) has revealed the presence of two non-equivalent iron atoms and a tetradeprotonated and heptadentate behaviour of the hydrazone involving a bridging action of both carbonyl groups.Keywords
