The molecule XeF82- has been reported, but the neutral complex,…
The molecule XeF82- has been reported, but the neutral complex, XeF8, is not known. Given that the molecule is proposed to have D4d symmetry (see picture), generate an MO diagram that uses the 5p orbitals from Xe and only the s-bonding p-orbitals from the 8 F atoms (represented by spheres in the drawing). Be sure […]
