The variation of the lattice parameters of TlBX2-type mixed crystals with composition have been investigated by X-ray diffraction technique. The lattice anisotropy (c/a) of the mixed crystals changes linearly depending on substitution of the atoms located both at the centre and at the vertices of the BX4 tetrahedra. For some of the mixed crystals studied, structural phase transition (monoclinic ⇌ tetragonal) is observed due to atom substitution when the sum of tetrahedral covalent radii of the B and X atoms in BX4 tetrahedra reaches a critical value of about 0.255 nm.
