T-shaped molecular geometry
In chemistry, T-shaped molecular geometry describes the structures adopted by some compounds where a central atom has three ligands. Ordinarily, three-coordinated compounds adopt trigonal planar or pyramidal geometries. Example of a T-shaped molecules are the halogen trifluorides, such as ClF3.
According to VSEPR theory T-shaped geometry results from three ligands and two lone pairs of electrons bonded to the central atom (known in AXE notation as AX3E2). The three atoms bond at 90° angles on one side of the central atom, producing the T shape.
