Square planar geometry

Square planar geometry is a way atoms arrange themselves around a central atom, forming a flat, four-sided shape similar to a square. In this structure, four atoms or groups are positioned at the corners of the square, all lying roughly in the same plane. This arrangement occurs because of specific electron interactions that minimize repulsion, providing stability. It’s common in certain metal complexes, especially with metals like platinum or palladium. The square planar shape influences the compound’s chemical properties, reactivity, and how it interacts with other molecules.
