Abstract We have successfully synthesized two novel compounds [$A_{6}$Cl][Fe$_{24}$Se$_{26}$] ($A$ = K, Rb). The key structural units of them are FeSe octamers, consisting of edge-shared FeSe$_{4}$ tetrahedra. Two kinds of FeSe octamer layers with different connection configurations stack along the $c$ axis, forming a three-dimensional (3D) TiAl$_{3}$-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 $T_{\rm N}\sim 110$ K and 75 K for [K$_{6}$Cl][Fe$_{24}$Se$_{26}$] and [Rb$_{6}$Cl][Fe$_{24}$Se$_{26}$].
