Synthesis and structural, magnetic and spectroscopic characterization of iron(iii) complexes with in situ formed ligands from methyl-2-pyridyl ketone transformations

Abstract

Reactions of methyl-2-pyridyl ketone, pyCOMe, with FeCl3·6H2O in various solvents gave complexes [Fe4Cl6(OMe)2(L1)2]·0.7MeCN·0.4MeOH (1·0.7MeCN·0.4MeOH) and [Fe3Cl4(bicine)(L2)]·Me2CO·0.2H2O (2·Me2CO·0.2H2O). The ligands (L1)2- = pyCO(Me)CH=COpy (in 1) and (L2)2- = pyCO(Me)CH2CO(OMe)py (in 2)...
