Synthesis of ternary and quaternary graphite intercalation compounds containing alkali metal cations and diamines.
A series of ternary graphite intercalation compounds (GICs) of alkali metal cations (M = Li, Na, K) and diamines [EN (ethylenediamine), 12DAP (1,2-diaminopropane), and DMEDA (N,N-dimethylethylenediamine)] are reported. These include stage 1 and 2 M-EN-GIC (M = Li, d(i) = 0.68-0.84 nm; M = Na, d(i) = 0.68 nm), stage 2 Li-12DAP-GIC (d(i) = 0.83 nm), and stage 1 and 2 Li-DMEDA-GIC (d(i) = 0.91 nm)...
متن کاملQuantum delocalization of molecular hydrogen in alkali-graphite intercalates.
The adsorption of molecular hydrogen (H2) in the graphite intercalation compound KC24 is studied both experimentally and theoretically. High-resolution inelastic neutron data show spectral features consistent with a strong pinning of H2 along a single axis. First-principles calculations provide novel insight into the nature of H2 binding in intercalates but fail to account for the symmetry of t...
متن کاملTernary Amides Containing Transition Metals for Hydrogen Storage: A Case Study with Alkali Metal Amidozincates.
The alkali metal amidozincates Li4 [Zn(NH2)4](NH2)2 and K2[Zn(NH2)4] were, to the best of our knowledge, studied for the first time as hydrogen storage media. Compared with the LiNH2-2 LiH system, both Li4 [Zn(NH2)4](NH2)2-12 LiH and K2[Zn(NH2)4]-8 LiH systems showed improved rehydrogenation performance, especially K2[Zn(NH2)4]-8 LiH, which can be fully hydrogenated within 30 s at approximately...
متن کاملThree alkali-metal-gold-gallium systems. Ternary tunnel structures and some problems with poorly ordered cations.
Six new intermetallic compounds have been characterized in the alkali metal (A = Na, Rb, Cs)-gold-gallium systems. Three isostructural compounds with the general composition A(0.55)Au(2)Ga(2), two others of AAu(3)Ga(2) (A = Rb, Cs), and the related Na(13)Au(41.2)Ga(30.3) were synthesized via typical high-temperature reactions and their crystal structures determined by single-crystal X-ray diffr...
متن کاملNew Hydrogen Peroxide Adducts of Alkali Metal Tetracyanoplatinates
The title compounds have been synthesized by adding hydrogen peroxide to an aqueous solution of A2[Pt(CN)4] (A = K, Rb, Cs). They grow as yellow needles after concentrating and cooling to 4 ◦C. The structures were elucidated from single crystal analysis. The isostructural compounds crystallize monoclinically, in space group C2/c with Z = 4. K2Pt(CN)4 ·H2O2: a = 13.3751(7), b = 11.2713(6), c = 6...
