The ternary rare-earth-metal nickel indides RE 23 Ni 7 In 4 (RE = Gd, Tb, Dy) were prepared by arc-melting mixtures of the elements followed by annealing at 870 K. They adopt the Yb 23 Cu 7 Mg 4 -type structure (space group P6 3 /mmc, Pearson symbol hP68, Z = 2), as determined by laboratory and synchrotron powder diffraction methods for RE = Gd (a = 9.6435(10) Å, c = 22.118(3) Å) and Tb (a = 9.5695(8) Å, c = 21.983(3) Å), and single-crystal X-ray diffraction methods for RE = Dy (a = 9.533(5) Å, c = 21.890(13) Å). The centrosymmetric Yb 23 Cu 7 Mg 4 -type structure is closely related to the noncentrosymmetric Pr 23 Ir 7 Mg 4 -type structure. Triangular In 3 clusters within RE 23 Ni 7 In 4 represent a rare type of cluster found among metal-rich indides; the reasons for their formation were investigated by density functional theory methods.
