Synthesis, Crystal Chemistry, and Semiconducting Properties of A3B14Se24 (A = Sn/Pb; B = In/Sb/Bi) with Step-Layered NaCl(111)-Type Slabs Interleaved by NaCl(100)-Type Ribbons

Key Points

• The aim is to identify the crystal structure and semiconducting properties of new multinary selenides A3B14Se24.
• Conducted exploratory synthesis in the (Sn/Pb)–In–(Sb/Bi)–Se systems.
• Characterized compounds using single-crystal X-ray diffraction to determine crystal structure.
• Identified new selenides, including Pb3In5Sb9Se24 and Sn3In5Sb9Se24.
• Established a step-layered NaCl(111)-type structure.
