Abstract

<abstract abstract-type="graphical" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>A viable alternative sandwich</bold> structure is presented, which does not contain any carbon atom. This <italic>D</italic>_{4<italic>h</italic>}‐symmetric inverse sandwich instead uses the "carbon‐like" phosphorus, which together with heavier elements of Group 13 (E = Al–Tl) forms a stable molecule. Density functional theory computations indicate that the sandwich form is more stable than a <italic>D</italic>_{2<italic>d</italic>} isomer of two perpendicular EP₂ units (except for E=B), and should be formed exothermically from white phosphorus and E₂.
