The molecular geometry of Xenon Tetrafluoride is square planar. Xenon has 4 bond pairs and 2 lone pairs, resulting in a square planar geometry.
Square planar and tetrahedral complexes are two common geometries in coordination chemistry. The key difference lies in their coordination number and shape. Square planar complexes have a coordination number of 4, with the central metal ion surrounded by four ligands in a flat, square arrangement. On the other hand, tetrahedral complexes have a coordination number of 4 as well, but the ligands are arranged in a three-dimensional tetrahedral shape around the central metal ion. This difference in geometry affects the overall stability and reactivity of the complex.
KrF4 is square planar with an octahedral electron geometry but square planar molecular geometry. It is a nonpolar molecule because the four fluorine atoms are arranged symmetrically around the central krypton atom, cancelling out any dipole moments.
The IF4- ion has a square pyramidal molecular geometry with the iodine atom at the apex and the four fluorine atoms at the base vertices.
The molecular shape of XeF4 is square planar. Xenon (Xe) has 4 bonding pairs and 2 lone pairs around it, resulting in a square planar geometry.
