| Why this differs from similar rows: BM3 fit to the low-pressure Hydrogen Off-Center (HOC) structure, 0-20 GPa, V0 free; sibling entry is the high-pressure H-bond-symmetrized (HC) structure fit over 30-140 GPa. | ||||||||||||||
| ε-FeOOH |

— | 58.62 ų Unit cell |
223 | 4.070 | third-order Birch-Murnaghan | — | Original | ||||||
| Why this differs from similar rows: BM3 fit to the high-pressure H-bond-symmetrized (HC) structure, 30-140 GPa; sibling entry is the low-pressure HOC structure over 0-20 GPa; symmetrization raised K0, lowered K'. | ||||||||||||||

205 | 1.090 | third-order Birch-Murnaghan | — | Original | ||||||
| Why this differs from similar rows: FeO6 polyhedral (not bulk unit-cell) EOS, low-pressure HOC structure, 0-20 GPa; sibling is the high-pressure HC structure fit over 30-140 GPa. | ||||||||||||||
