- The crystal structures of two low temperature B8(2) related superstructure phases in the nickel indium system, Ni13In9 and Ni7-delta In3, have been refined and described in relation to the underlying parent Ni2In structure-type. They are isostructural to In13Pt9 and Cu7In3, respectively and both accommodate the change in stoichiometry from Ni2In by forming "same atom" structural motifs, In-centred indium octahedral units in the case of Ni13In9 and trigonal bipyramidal nickel units in the case of Ni7-delta In3. A sample with the nominal composition Ni51n3, reported to form part of a solid solution in the binary phase diagram, is not stable at 400 degrees C and forms a two-phase mix of Ni7-delta In3 and Ni13In9.
