Square antiprismatic molecular geometry

Square antiprismatic molecular geometry

In chemistry, the square antiprismatic molecular geometry describes the shape of compounds where eight atoms, groups of atoms, or ligands are arranged around a central atom, defining the vertices of a square antiprism.

Examples

XeF₈²⁻
IF₈⁻
ReF₈⁻
ZrF₈⁴⁻
