Reported values remain attached to the sample, method, conditions, extraction quality and source location that produced them.
Cu-HAB powder · Powder
As-synthesised sample suspended in 0.1 M KOH for 24 h at room temperature, washed, dried, degassed and characterised by PXRD.
| Property | Reported value | Normalised value | Uncertainty | Origin and quality | Source |
|---|---|---|---|---|---|
| Cu-HAB PXRD stability after KOH | PXRD peak intensity decreased after 0.1 M KOH treatment. | — | — | Caption Qualitative | S3 · Figure caption · Figure S2 |
Ni-HAB-H high-crystallinity powder · Powder
Cu-sealed tube, lambda = 1.54 A, capillary, 50 kV and 1 mA; compared before and after 0.1 M KOH buffer treatment.

| PXRD structure assignment for Ni-HAB-H | Good agreement with previously reported 2D honeycomb eclipsed M-HAB structure; PXRD maintained after KOH buffer treatment. | — | — | Qualitative Qualitative | 39076 · Synthesis of Ni-HAB-H and Ni-HAB-L · Figure 2a |
Ni-HAB-L low-crystallinity powder · Powder
Cu-sealed tube, lambda = 1.54 A, capillary, 50 kV and 1 mA; compared before and after 0.1 M KOH buffer treatment.
| Property | Reported value | Normalised value | Uncertainty | Origin and quality | Source |
|---|---|---|---|---|---|
| PXRD structure assignment for Ni-HAB-L | Same Ni-HAB structure as Ni-HAB-H but lower crystallinity; PXRD maintained after KOH buffer treatment. | — | — | Qualitative Qualitative | 39076 · Synthesis of Ni-HAB-H and Ni-HAB-L · Figure 2a |
