title: 4-Thioxo-3,5-dithia-1,7-hepta-nedioic acid.
abstract: The complete molecule of the title compound, C(5)H(6)O(4)S(3), is generated by crystallographic twofold symmetry with the C=S group lying on the rotation axis. The molecules are linked through weak hydrogen-bond contacts by glide-plane operations to form R(2) (2)(20) rings and ladder-like C(4) chains along the c axis.
