Redetermination of diammonium thiomolybdate
In contrast to the previous structure determinations of the title structure, (NH(4))(2)[MoS(4)], the present determination at 173 K localized the positions of the H atoms. The title structure belongs to the β-K(2)SO(4) family and all the ions are located on crystallographic mirror planes. The ions are held together by N-H⋯S hydrogen bonds (some of which are bifurcated), forming a three-dimensio...
متن کاملRedetermination of trans-cyclohexane-1,4-diammonium dichloride
A redetermination of the crystal structure of the title compound, C(6)H(16)N(2) (2+)·2Cl(-), was undertaken. All atomic coordinates including those of the H atoms were refined freely. The cation is located on a centre of symmetry. Important for the crystal structure are wavy hydrogen-bonded layers that are formed by ammonium groups and chloride anions, giving hydrogen-bonded rings.
متن کاملEthane-1,2-diammonium dibromide: a redetermination at 100 K
In the redetermined [for the previous study, see Søtofte (1976 ▶). Acta Chem. Scand. Ser. A, 30, 309-311] crystal structure of the title compound, C(2)H(10)N(2) (2+)·2Br(-), the H atoms have been located and the hydrogen-bonding scheme is described. The ethane-1,2-diammonium cation lies over a crystallographic inversion centre and straddles a crystallographic mirror plane with the C and N atoms...
متن کاملA new sodium dimangnesium trivanadate, NaMg2V3O10
A single crystal of NaMg(2)V(3)O(10) has been prepared by solid-state reaction at 1173 K. The [Mg(2)(V(3)O(10))](-) anions are built up from edge-sharing MgO(6) octa-hedra to form [Mg(4)O(18)] units, which are linked to each other by trivanadate groups (V(3)O(10)). The Na(+) ions are located in the tunnel space.
متن کاملDiammonium biphenyl-4,4′-disulfonate
In the title salt, 2NH(4) (+)·C(12)H(8)O(6)S(2) (2-), the dianion has crystallographic inversion symmetry. A three-dimensional framework is formed from primary hydrogen-bonded sheet structures comprising ammonium N-H⋯O(sulfonate) inter-actions and is linked peripherally through the biphenyl residues of the anions. This open framework has 43 Å(3) solvent-accessible voids.
