摘要：We have successfully synthesized two novel compounds [A(6)Cl][Fe24Se26] (A = K, Rb). The key structural units of them are FeSe octamers, consisting of edge-shared FeSe4 tetrahedra. Two kinds of FeSe octamer layers with different connection configurations stack along the c axis, forming a three-dimensional (3D) TiAl3-type structure. Interestingly, the 3D structural topology of these ocatmers in one unit cell is similar to the local atomic arrangement of themselves, i.e., self-similarity in struct ...More
We have successfully synthesized two novel compounds [A(6)Cl][Fe24Se26] (A = K, Rb). The key structural units of them are FeSe octamers, consisting of edge-shared FeSe4 tetrahedra. Two kinds of FeSe octamer layers with different connection configurations stack along the c axis, forming a three-dimensional (3D) TiAl3-type structure. Interestingly, the 3D structural topology of these ocatmers in one unit cell is similar to the local atomic arrangement of themselves, i.e., self-similarity in structure. Physical property characterizations indicate that both the compounds exhibit insulating antiferromagnetism with Neel temperatures T-N similar to 110 K and 75 K for [K6Cl][Fe24Se26] and [Rb6Cl][Fe24Se26]. ...Hide
