Isolated versus Condensed Anion Structure III: The Influence of the Cations 1,3-propanediammonium, 1,4-butanediammonium, /t-propylammonium, /i-butylammonium and /i-pentylammonium on Structures and Phase Transitions of ZnBrJ" Salts. A Br NQR and X-ray Structure Analysis
The influence of the cations on the condensation of the anions in the salts (A')Zn(II) Br4 and (A)2Zn(II)Br4 is studied by 81 Br NQR and X-ray crystal structure analysis. (A')Zn(II)Br4(A' = [H3N(CH2)3NH3] + ) (1) shows a phase transition at 474 K. The phase II of (1) crystallizes with isolated [ZnBrJ " tetrahedra: monoclinic P2 t/«, Z = 4, a = 1108.4 (5), b = 1096.8 (2), c = 1118.5 (6) pm, and ...
متن کاملIsolated versus Condensed Anion Structure VI: X-ray Structure Analysis and 81 Br NQR of Guanidinium Pentabromodicadmate(II), [C(NH2)3]Cd2Br5, fns-Hydrazinium Pentabromocadmate(II), [H2NNH3]3CdBr5, and fo's-Hydrazinium Tetrabromocadmate(II)-Tetra Hydrate, [H2NNH3]2CdBr4-4H20
The structure of the condensed bromocadmate anions in [C(NH2)3]Cd2Br5 (1) and [H2NNH3]3CdBr5 (2) were studied at room temperature by X-ray diffraction. (1) crystallizes with double-chains bridged by Br atoms (orthorhombic, Pmmn, Z = 2, a = 1394.0(5), b = 394.5(1), c = 1086.9(5) pm). This chain structure was not described previously. (1) shows three 8 'Br NQR lines at temperatures between 77 and...
متن کاملA second polymorph of [H3N(CH2)3NH3][V4O10].
The title compound, propane-1,3-diammonium tetravanadate, (C3H12N2)[V4O10], represents a second polymorph of composition beta-[H3N(CH2)3NH3][V4O(10)]. It differs from the alpha polymorph [Riou & Ferey (1995). J. Solid State Chem. 120, 137-145] in the conformation of the propane-1,3-diammonium dication which, in the present example, lies on a twofold axis and adopts a syn-syn rather than a syn-a...
متن کاملCompatibility of B-Sheets with Epitopes Predicted by Immunoinformatic in Human IgG
Background & Aims: Antibodies, well-known as immunoglobulins (Igs), are produced by B lymphocytes and specifically defend against pathogens. Igs are glycoproteins and have high diagnostic value in several diseases including infections (1). Igs are composed of light and heavy chains (2, 3). Each chain is comprised of about 110-120 amino acid residues which create immunoglobulin folds named domai...
متن کامل35 C 1 NQR and X - Ray Studies of Hexachloropalladates A 2 PdCl
The 35C1 NQR frequencies o f A 2PdCl6 were studied. For A = (CH3)4N + a clathrate [(CH3)4N]2PdCl6 Cl2 was found and its crystal structure was determined (F d3c, Z = 32, a = 2554.5 pm, R = 0.062). The clathrate [(CH3)4N]2SnCl6 Cl2 was prepared, too. It is isomorphous with the corresponding palladium salt. The results o f the 35C1 NQR studies are discus sed on the basis o f the crystal structure.
