Graphical abstract
La3Sb3Co2O14crystallizes in a pyrochlore related structure with an ordered distribution of cations, giving rise to two sets of ideal 2D Kagome lattices formed by La3+or Sb5+respectively. This rhombohedral pyrochlore is a tolerant structure for stable compounds composed by many light rare-earth and d-transition elements. Substituting Zn2+or Mg2+for Co2+will provide a series of compounds useful for studying magnetic interactions in the rare-earth Kagome lattices.
