The molecular structures of 1-benzyl-2-ethyl-3-hydroxypyridin-4-one hydrate [(1), C14H15NO2. H2O], 2-ethyl-3-hydroxy-1-(4-methylbenzyl)pyridin-4-one [(2), C15H17NO2], 2-ethyl-1-(4-fluorobenzyl)-3-hydroxypyridin-4-one [(3), C14H14FNO2] and 2-ethyl-3-hydroxy-1-(4-trifluoromethylbenzyl)pyridin-4-one hemihydrate [(4), C15H14F3NO2. 0.5H(2)O] have been determined. The compounds all exhibit mutually hydrogen-bonded dimeric pairs. In the case of (1) and (2), the molecules of the dimer are symmetry related, while in (3) and (4), two independent molecules of the asymmetric unit are linked. For the hydrates (1) and (4), the dimeric pairs are linked by further hydrogen bonds through the water molecules.
New lipophilic 3-hydroxy-4-pyridinonate iron(<scp>iii</scp>) complexes: synthesis and EXAFS structural characterisation
analysis and thermogravimetric measurements indicates that most of the complexes are obtained as hydrates of general formula ML3·xH2O. Structural characterization of these difficult to crystallize lipophilic complexes has been achieved by EXAFS spectroscopy. Solutions of iron(III) complexes of maltol, ethylmaltol, 1,2-dimethyl-3-hydroxy-4-pyridinone and 1-phenyl-2-methyl-3-hydroxy-4-pyridinone in methanol–water
