N‐Methylthiocarbamoyltetrathiafulvalene at 150 K

The crystal structure of the title compound, 4-(N-methylthiocarbamoyl)-2,2'-bi(1,3-dithiolylidene), C 8 H 7 NS 5 , has been re-determined at 150 K and is compared with that determined by an ambient-temperature study, showing essentially the same motif (κ packing of dimers) and strongly anisotropic thermal expansion
