The Jahn-Teller (JT) theorem constitutes one of the most fundamental concepts in chemistry. In transition-element chemistry, the 3d<sup>4</sup> and 3d<sup>9</sup> configurations in octahedral complexes are particularly illustrative, where a distortion in local geometry is associated with a reduction of the electronic energy. However, there has been a lasting debate about the fact that the octahedra are found to exclusively elongate. In contrast, for Na<sub>9</sub> Bi<sub>5</sub> Os<sub>3</sub> O ...[more]
