摘要：

A crystallographic analysis is performed for the structures of TlCu2S2, TlCu7S4, TlTaS3, TlIn3S5, TlIn5S8, and TlCr2V3S8. In them the Tl+ cation is included in anion sublattices and stabilizes their regularity. The cation sublattices are substantially distorted and have additional conjugation to the anionic positions of the thallium cations. The monoclinic structures (the last three) have geometrically similar anionic and cationic "forced skeletons," while in tetragonal (the first two) and orthorhombic symmetries they are modified by symmetry restrictions.
