title: Redetermination of diammonium thio-molybdate.
abstract: 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.
