The IOF6(-)Anion: The First Example of a Pentagonal Bipyramidal AX5YZ Species

Abstract

In main group element chemistry, coordination numbers in excess of six are relatively rare, but they are of considerable interest due to special features caused by steric crowding of the ligands, free valence electron pairs being sterically either active or inactive, and the propensity of the molecules to exhibit fluxionality. Of particular interest are heptacoordinated species which could exist either as a monocapped octahedron, a monocapped trigonal prism, or a pentagonal bipyramid. According to the VSEPR model of 'repelling points on a sphere', the preferred structures should be the monocapped octahedron or trigonal prism
