La-Ni-Si: A Gold Mine with a Diamond.

ABSTRACT: The La-poor part of the ternary La-Ni-Si system has been explored leading to the discovery and structural characterization of four new polar intermetallic compounds. LaNi₅Si₂ [BaAu₅Ga₂ type, oP64, space group Pnma, a = 7.8223(7) Å, b = 6.3894(6) Å, c = 17.843(2) Å, V = 891.8(2) ų, Z = 8] features a diamond (lonsdaleite)-like homoatomic Ni framework and is the first Ni representative of a larger family of compounds typically formed by aurides. La₂Ni₈Si₃ [Eu₂Ni₈Si₃ type, tP52, P4₂/nmc, a = 10.0278(3) Å, c = 7.5047(4) Å, V = 754.65(6) ų, Z = 4] is charac
