Variation of the lattice parameters of TlTl1-xInxSe2 chain mixed crystals with composition have been studied by X-ray diffraction technique. The lattice anisotropy (c/a) of the TlBX2-type mixed crystals changes linearly with substitution of the atoms located bath at the center and at the vertices of the BX4 tetrahedra. A brief survey of the important features of the effect of isomorphic atom substitution on the lattice anisotropy of TlBX2-type mixed crystals with chain structure has been presented.
