Resumen
En este paper presentamos una búsqueda sistemática de compuestos binarios que cristalizan en el grupo espacial quiral P6222 con el objetivo de identificar nuevos metales Kagome quirales. Mediante la combinación de un análisis de posiciones de Wyckoff con radios iónicos de Shannon y estados de oxidación, establecemos correlaciones entre el tamaño atómico, la valencia y la ocupación preferencial de sitios cristalográficos, particularmente del sitio 3d que forma las redes Kagome. El análisis de más de 300 estructuras revela que los cationes de menor tamaño tienden a ocupar preferentemente las posiciones 3d d, mientras que los iones de mayor tamaño se ubican en sitios periféricos (3c, 6j). Los prototipos basados en calcio e iridio exhiben estados magnéticos diferenciados y respuestas contrastantes al acoplamiento espín–órbita, a pesar de compartir la misma simetría cristalina, lo cual evidencia el papel determinante de la coordinación local en la topología electrónica resultante. Estos hallazgos proporcionan principios de diseño fundamentales para la síntesis dirigida de nuevos materiales Kagome quirales con propiedades comparables a las de Fe3Sn2 y CoSn.
