According to the
Linear geometry also occurs in AX2E3 molecules, such as xenon difluoride (XeF2)[3] and the triiodide ion (I−3) with one iodide bonded to the two others. As described by the VSEPR model, the five valence electron pairs on the central atom form a trigonal bipyramid in which the three lone pairs occupy the less crowded equatorial positions and the two bonded atoms occupy the two axial positions at the opposite ends of an axis, forming a linear molecule.
