Condensed double chains of edge‐sharing scandium octahedra are contained in Sc 2 Te. These structural units are augmented by more loosely bound pyramidal and zigzag scandium aggregates. On the right is a projection of these chains together with tellurium (the open circles). The metal array may be viewed as the result of the dissociation of the metal framework in electron‐richer chalcogenides.
