Organic 2,5-dihydroxy-1,4-benzoquinone potassium salt with ultrahigh initial coulombic efficiency for potassium-ion batteries

Here, we propose a new organic 2,5-dihydroxy-1,4-benzoquinone potassium salt (K2C6H2O4) endowing an ultrahigh initial coulombic efficiency of 96% as an advanced anode for potassium-ion batteries. Theoretical calculations and experimental results suggest that K+ can reversibly insert into this organic compound due to the flexible and stable structure of the K2C6H2O4 molecule as well as fast K+ kinetics in the selected dimethyl ether-based electrolyte.

Face-to-face stacking of dianionic quinoid rings in crystals of alkali salts of 2,5-dihydroxyquinone in view of π-system polarization

A series of alkali (M+ = K+, NH4 +, Rb+ and Cs+) salts of 2,5-dihydroxyquinone [M2+ (C6H4O4) 2-] was prepared and their structures were determined by X-ray structure analysis. A less-common type of π-stacking of dianionic quinoid rings in face-to-face fashion (no offset) is observed. However, in the potassium salt of this series the stacking motif of the dianionic quinoid rings is in a herring-bone pattern, usually observed in the stacking of aromatics. The different types of crystal structures, induced by varied cations, are discussed in terms of the relative energies calculated by the DFT method. The structural features observed were reproduced by the calculations. The stacking of the quinoid rings is assisted by dispersion interactions. The Royal Society of Chemistry.

Tetradihydrobenzoquinonate and tetrachloranilate Zr(IV) complexes: Single-crystal-to-single-crystal phase transition and open-framework behavior for K4Zr(DBQ)4

The molecular complexes K4[Zr(DBQ)4] and K 4[Zr(CA)4], where DBQ2- and CA2- stand respectively for deprotonated dihydroxybenzoquinone and chloranilic acid, are reported. The anionic metal complexes consist of Zr(IV) surrounded by four O,O-chelating ligands. Besides the preparation and crystal structures for the two complexes, we show that in the solid state the DBQ complex forms a 3-D open framework (with 22% accessible volume) that undergoes a crystal-to-crystal phase transition to a compact structure upon guest molecule release. This process is reversible. In the presence of H2O, CO2, and other small molecules, the framework opens and accommodates guest molecules. CO2 adsorption isotherms show that the framework breathing occurs only when a slight gas pressure is applied. Crystal structures for both the hydrated and guest free phases of K4[Zr(DBQ)4] have been investigated.
