Studies on the coordinate bond. VII. Complexes of diimines with iron, synthesis and spectral properties.

In order to investigate the spectral properties of iron diimine complexes a new series of complexes was synthesized and characterized. Their electronic spectra were studied including solid state liquid nitrogen temperature (LNT) measurements. This study showed that in the case of the ferrous complexes three metal to ligand electron transfer (MLET) bands can be observed, in the visible region, although many authors have assigned them to vibrational structure of the main band. The d-d bands in the spectra of the ferrous complexes are discussed. Very intense internal ligand electron transfer (lLET) bands are observed in the UV region and discussed. In the case of the ferric complexes we observed two ligand to metal electron transfer (LMET) bands in the visible region and lLET bands in the UV region. A correlation between the energy of these transitions in the ferrous and ferric complexes is discussed.

Crystal and molecular structure of a nickel(II) macrocyclic tetra-imine complex: 5,7,7,12,12,14-hexamethyl-1,4,8,11-tetra-azacyclotetradeca-4,8,10,14-tetraenenickel(II) perchlorate

The structure of the title compound has been determined by single-crystal X-ray analysis from photographic data and refined by least-squares techniques to R 0·12 for 1229 independent reflections. Crystals are orthorhombic, space-group Pbcn, with a= 10·62, b= 11·18, and c= 18·81 Å, Z= 4. A crystallographic two-fold axis lies in the approximate plane of the macrocyclic cation, requiring the nickel ion to lie in the mean plane of the four nitrogen atoms, these deviate ± 0·18 Å from the co-ordination plane, indicating some lack of flexibility in the macrocycle. Strain in the complex is also discussed in terms of deviations of the macrocycle bond and torsion angles from the expected strain-free values. This complex is compared with the related di-imine complex 5,7,7,12,12,14-hexamethyl-1,4,8,11-tetra-azacyclotetradeca-4,14-dienenickel(II) perchlorate.
