Square planar complex

A square planar complex is a type of chemical structure where a central metal atom (often transition metals like platinum or palladium) is surrounded by four smaller atoms or molecules called ligands. These ligands are arranged at the corners of a flat, square-shaped plane around the metal. The shape results from the way electrons are shared and distributed, allowing the complex to be stable. This geometry influences the complex’s chemical properties and reactivity, making it important in fields like catalysis and medicine. In essence, it’s a flat, square arrangement of components bound to a central metal.
