A series of molecular rare-earth telluride clusters incorporating a three-centre, four-electron, tri-tellurido ligand (Te34−) are reported. These atomically precise clusters, possessing ultralow band gaps comparable to those of monocrystalline silicon and gallium arsenide, are potentially applicable as quantum materials and for optoelectronic applications.
