Magnetic ground-states of stable compounds. a A Cs4MB2X12 with different AFM configurations. Voids between the octahedrons are filled with Cs atoms, which are omitted for clarity. Arrows denote the spin directions. b Magnetic ground-states for the seven stable Cs4MB2X12 compounds. c Schematic diagram of electron occupation of M2+ in Cs4M2+Bi2Cl12 (M2+ = Mn2+/Fe2+/Cu2+) and M4+ in Cs4M4+Pb2Cl12 (M2+ = Mn2+/Fe2+). d Schematic diagram of FM coupling in Cs4FePb2Cl12.
