title: Ethane-1,2-diammonium dibromide: a redetermination at 100 K.
abstract: 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 in special positions. In the crystal, the cations and anions are linked by N-H⋯Br and N-H⋯(Br,Br) hydrogen bonds, which generate various ring and chain motifs including an R(10) (5)(32) loop.
