T-shaped molecular geometry
- T-shaped molecular geometry
In chemistry, T-shaped molecular geometry describes a somewhat unusual geometry adopted by compounds where a central atom has three ligands. Ordinarily, three-coordinated compounds minimize the steric repulsion between the ligands by adopting trigonal planar geometry. According to VSEPR theory this geometry results from three ligands and two lone pairs of electrons bonded to the central atom. The three atoms bond at 90° angles on one side of the central atom, producing the T shape.
