✦ Synopsis

Abstract

A complex from Fe(II) and a hexa-dentate linear ligand containing O~2~N~4~ donor atoms were prepared and the structure enlightened with X-ray diffraction. The Fe(II) ion in the complex was seen to be oxidized to form a Fe(III) complex, [C~20~H~24~Cl~3~N~4~O~2~]Fe and the three chloride ions were situated at a distance of Fe…Cl(1) 3.976(5), Fe…Cl(2) 4.479(3) and Fe…Cl(3) 7.509(4) Å outside the coordination sphere. The Fe(III) ion has an octahedral coordination sphere and as expected the two oxygen donor atoms are coordinated in a -cis position. The Fe—O, Fe—N~imin~ and Fe—N~amine~ distances are 1.880(3) Å, 1.931(4) Å and 2.004(4) Å, respectively.
