The interactions between quaternary compounds A^I₂B^IIС^IVX₄ have been investigated. For the Cu₂CdGeS₄–Cu₂CdSnS₄ and Cu₂ZnGeSe₄–Cu₂CdGeSe₄ systems polythermal sections were constructed. In the zinc-containing systems, the extent of the solid solutions based on the end compounds were investigated. The largest solid solution width was observed along the Cu₂ZnGeS₄–Cu₂ZnSiS₄ section, where Cu₂ZnSiS₄ extends up to 50 mol.%.
