Ga<sub>5</sub>Li<sub>12</sub><sup>+</sup>: A Doubly Aromatic Ga<sub>5</sub><sup>11–</sup> Ring Stabilized by Lithium Cations
Ga<sub>5</sub>Li<sub>12</sub><sup>+</sup> features a planar, <i>D</i><sub>5<i>h</i></sub>-symmetric Ga<sub>5</sub><sup>11-</sup> ring stabilized by two [Li<sub>6</sub>]<sup>6+</sup> caps and exhibits dual 6π- and 10σ-electron aromaticity. Structural, electronic delocalization, and magnetic criteria consistently confirm its doubly aromatic character. This cluster represents the first example of a Ga<sub>5</sub> ring stabilized by six π-electrons, expanding the scope of main-group aromaticity.
