Carbonyl diisothiocyanate (1) and oxalyl diisothiocyanate (2) were synthesized by reactions of phosgene and oxalyl chloride with ammonium thiocyanate, respectively. Their structures were elucidated by single-crystal X-ray diffraction. 1 exhibits weak intermolecular S–O contacts forming a loosely connected network of molecules, whereas 2 exhibits weak intermolecular Ccarbonyl–O contacts resulting in
