Square planar

Square planar describes a specific way certain molecules arrange their atoms. Imagine a central atom with four other atoms attached around it, positioned at the corners of a flat square. This geometric shape results from the way electrons and bonds balance out, leading the molecule to adopt a square shape. It’s common in some transition metal complexes, especially with metals like platinum or palladium. This arrangement influences the molecule's properties, such as reactivity and stability, and helps scientists understand how these molecules interact in chemical reactions.
