Abstract

A new binary phase, Cu10In7, was found during the investigation of the η?-phase field in the Cu-In system. Single crystals of 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)A ° , b = 11.8462(1)A ° , c = 6.7388(1)A ° and ?β = 91.063(1). The structure is based on a unit of face-sharing octahedra consisting of five Cu4In2 octahedra terminated by Cu5In octahedra at both ends. The crystal structure is closely related to the Cu11In9 structure type.
