Graphical Abstract
A twelve-membered ring made up of Fe2+ ions is present in the cluster framework of 1 (shown on the right without phenyl groups; Fe atoms are white, Se atoms shaded). The Fe2+ ions are located in the centers of edge-sharing Se4 tetrahedra, which in turn form a ring. The shiny black needles of 1 are prepared from FeCl3, PPh3, and PhSeSiMe3, and decompose readily upon heating.
