caption_attribution_description: English: Structure of Xenon tetraflouride, one of the first noble gas compounds to be discovered.
context_page_description: The square planar molecular geometry in chemistry describes the stereochemistry that is adopted by certain chemical compounds. As the name suggests, molecules of this geometry have their atoms positioned at the corners of a square on the same plane about a central atom.
context_section_description: Square-planar coordination geometry violates the points-on-sphere geometries observed from most compounds (i.e. linear, trigonal, tetrahedral, trigonal bipyramidal, ...). The isolation of both trans- and cis-PtCl₂(NH₃)₂ led Alfred Werner to propose square planar molecular geometry.
