Octahedral = sp3d2, Tetrahedral = sp3, Square planar = dsp2.
The geometry of a molecule/complex is decided by the type of hybrid orbitals the central atom uses. Each geometry corresponds to a definite number and type of hybrid orbitals:
(a) Octahedral (6 directions at 90°): the central atom uses six equivalent hybrid orbitals, formed by mixing one s, three p and two d orbitals → sp3d2 (or, using inner d orbitals, d2sp3). Example: SF6. …
