Mixed-anion compounds are generally considered to be decomposition-melting type, so it is difficult to grow large single crystals by melt-growth method. In our previous presentation, we successfully synthesized single crystal of layered mixed-anion compound Sr₂ZnCu₂Se₂O₂. To understand the crystal growth mechanism, we performed thermal analysis and found that Sr₂ZnCu₂Se₂O₂ is congruent melting type in closed environment. Therefore, it is expected to grow large single crystals by melt-growth method.
