A New Compound in the Cu-In System : the Synthesis and Structures of Cu10In7

• A new binary phase, Cu10In7, was found during the investigation of the eta-phase field in the Cu-In system. Single crystals Cu10In7 were grown from a melt under an inert atmosphere. The compound crystallizes in the monoclinic space group C2/m with cell parameters a = 13.8453(2) angstrom, b = 11.8462(1) angstrom, c = 6.7388(1) angstrom and beta = 91.063(1). The structure is based on a unit of face-sharing octachedra consisting of five Cu4In2 octahedra terminated by Cu5In octahedra at both ends. The crystal Structure is closely related to the Cu11In9 structure type.
