4-Thioxo-3,5-dithia-1,7-heptanedioic acid
Abstract
The complete molecule of the title compound, C5H6O4S3, 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 R22(20) rings and ladder-like C(4) chains along the c axis.
