Redetermination of diammonium thiomolybdate
نویسندگان
چکیده
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-dimensional network. One of the N atoms has nine contacts to the S atoms shorter than 4 Å, and the other has ten.

Redetermination 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.

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 کاملRedetermination of (NH4)2HAsO4
In comparison with the original determination based on Weissenberg film data [Khan et al. (1970 ▶). Acta Cryst. B26, 1889-1892], the current redetermination of diammonium hydrogenarsenate(V) reveals all atoms with anisotropic displacement parameters and all H atoms localized. This allowed an unambiguous assignment of the hydrogen-bonding pattern, which is similar to that of the isotypic phospha...
