The bond distribution of Cr–, Mn–, Fe–, and Co–kaolinite. Multi-magnetic states are given for each TM–kaolinite. The averaged different types of O–H (black), Si–Oa (black), Si–Ob (black), M–OHinter (red), M–OHinner (green), and M–O (blue) bonds in kaolinite are indicated by dot lines. The M–OHinter (red), M–OHinner (green), and M–O (blue) bonds in Cr–kaolinite (AFM), Mn–kaolinite (FM), Fe–kaolinite (AFM), and Co–kaolinite (NM) are indicated by solid lines
