Research Abstract

Crystal chemical study of FeVO4and Pb4Fe3O8Cl, with five-fold coordinated Fe3+, by single crystal X-ray diffraction has been conducted to obtain important knowledge for the relationship between the effective ionic radius and the chemical bonding nature of five-fold coordinated Fe3+. The Fe3+O bond lengths have precisely been dertermined, and Fe3+O bonds with square pyramidal coordination have been suggested to have stronger covalency than those with trigonal bipyramidal coordination.
