Pentagonal planar molecular geometry explained

Examples:
Symmetry Group:D5h
Atom Direction:5
Bond Angle:72°
Mu:0

In chemistry, the pentagonal planar molecular geometry describes the shape of compounds where five atoms, groups of atoms, or ligands are arranged around a central atom, defining the vertices of a pentagon.

Examples

The only two pentagonal planar species known are the isoelectronic (nine valence electrons) ions (pentafluoroxenate(IV)) and (pentafluoroiodate(III)).[1] Both are derived from the pentagonal bipyramid with two lone pairs occupying the apical positions and the five fluorine atoms all equatorial.
