The cubic SBU Ni₈X₆L₆ (X = OH⁻/H₂O, L = ligand) is of great interest due to its stability and potential applications when integrated in MOFs. Here, we investigate by detailed DRIFTS measurements and exchange reactions whether it is found to be neutral in MOFs, as previously assumed in the literature, or whether it can show anionic character, as observed in complexes.

阴离子还是中性？Ni8立方体在金属-有机骨架化合物中的电荷

立方 SBU Ni ₈ X ₆ L ₆ (X = OH ^- /H ₂ O, L = 配体) 由于其在 MOF 中的稳定性和潜在应用而备受关注。在这里，我们通过详细的 DRIFTS 测量和交换反应来研究它是否在 MOF 中是中性的，如文献中先前假设的那样，或者它是否可以显示出阴离子特性，如在配合物中观察到的那样。
