Nuclear relaxation in tetramethyltetraselenafulvalene salts (TMTSF) 2X, (X = PF6, ClO4)
2014 The nuclear spin-lattice relaxation of methyl-protons in (TMTSF)2ClO4 is measured versus temperature between 330 and 40 K. The relaxation from the hyperfine coupling to the itinerant electrons is found to be dominant above 200 K. Similar conclusions apply to (TMTSF)2PF6. At 300 K two regimes of relaxation are identified versus magnetic field : (i) a low-field regime (2-25) kOe where 1/T1 i...
متن کاملCrystal structures of Sr(ClO4)2·3H2O, Sr(ClO4)2·4H2O and Sr(ClO4)2·9H2O
The title compounds, strontium perchlorate trihydrate {di-μ-aqua-aquadi-μ-perchlorato-strontium, [Sr(ClO4)2(H2O)3] n }, strontium perchlorate tetra-hydrate {di-μ-aqua-bis-(tri-aqua-diperchloratostrontium), [Sr2(ClO4)4(H2O)8]} and strontium perchlorate nona-hydrate {hepta-aqua-diperchloratostrontium dihydrate, [Sr(ClO4)2(H2O)7]·2H2O}, were crystallized at low temperatures according to the solid-...
متن کاملCrystal structures of Ca(ClO4)2·4H2O and Ca(ClO4)2·6H2O
The title compounds, calcium perchlorate tetra-hydrate and calcium perchlorate hexa-hydrate, were crystallized at low temperatures according to the solid-liquid phase diagram. The structure of the tetra-hydrate consists of one Ca(2+) cation eightfold coordinated in a square-anti-prismatic fashion by four water mol-ecules and four O atoms of four perchlorate tetra-hedra, forming chains parallel ...
متن کاملCrystal structure of barium perchlorate anhydrate, Ba(ClO4)2, from laboratory X-ray powder data
The previously unknown crystal structure of barium perchlorate anhydrate, determined and refined from laboratory X-ray powder diffraction data, represents a new structure type. The title compound was obtained by heating hydrated barium perchlorate [Ba(ClO4)2·xH2O] at 423 K in vacuo for 6 h. It crystallizes in the ortho-rhom-bic space group Fddd. The asymmetric unit contains one Ba (site symmetr...
متن کامل$mathcal{X}$-injective and $mathcal{X}$-projective complexes
Let $mathcal{X}$ be a class of $R$-modules. In this paper, we investigate ;$mathcal{X}$-injective (projective) and DG-$mathcal{X}$-injective (projective) complexes which are generalizations of injective (projective) and DG-injective (projective) complexes. We prove that some known results can be extended to the class of ;$mathcal{X}$-injective (projective) and DG-$mathcal{X}$-injective ...
