and X-ray diffraction data. The cation [Fe(L – L)2Cl2]+ has been assigned a trans-octahedral structure. The nitrate complex of mdpo has a dimeric trigonal bipyramidal cation while the complex of edpo has a cis-octahedral structure. The nitrate complexes of tmdpo and hmdpo also have trigonal bipyramidal structure.
