Identify the geometry of the complex ion if the hybridization is d2sp3. linear square planar octahedral trigonal planar tetrahedral

Octahedral is the geometry of the complex ion which has d2sp3 hybridization.

The octahedral has eight faces hence the prefix octa. Octahedral molecular geometry describe the shape of compound with six atom or groups of atoms or ligands symmetrically arranged around a central atom. The octahedron is one of the platonic solids.
