a Definition of the critical points based on the proposed cationic polarization factor of Li3−3xDy1+xCl6, Li3−3xHo1+xCl6, Li3-3xY1+xCl6, and Li3-3xEr1+xCl6 halides (see Supplementary Table 13 for details). b XRD patterns of the targeted Li2.82Ho1.06Cl6, Li2.83Y1.057Cl6, and Li2.91Er1.03Cl6 samples and the standard references. Cationic polarization factor and its application in designing different-structured halides through both lithium content and M3+ regulation. c Definition of the two points based on the proposed cationic polarization factor of Li3-3x(Ho1-yIny)1+xCl6 halides along the line through hcp-T typed Li3HoCl6 to ccp-M typed Li2.727In1.091Cl6 (see Supplementary Table 14 for details). d XRD patterns of the targeted Li2.93Ho0.81In0.21Cl6 and Li2.85Ho0.525In0.525Cl6 samples and the standard references. ccp-M indicates the C2/m space group, hcp-T indicates the P3̅m1 space group, and hcp-O indicates the Pnma space group.
