Reactions of carbon with a heavy main group metal (M = Sb, Bi, or Te) in an excess of lanthanum/nickel eutectic flux lead to formation of a family of carbide compounds La3MC2with a new structure type. The monoclinic structure features C24−anions octahedrally coordinated by six La3+cations, andManions surrounded by 8 La3+cations. These compounds are not charge‐balanced and lie on the border between intermetallic carbides and mixed anion salts. Density of states calculations show a pseudogap at the Fermi level for La3BiC2, which indicates that this compound is a poor metal with optimized LaBi bonding interactions.more » « less
