Thionitrosyl radical

Dissociative ionization of [l,2,5]thiadiazolo[3,4-f][ l,2,5]thiadiazole 6 was found to be an efficient preparative route to in j// -generated thionitrosyl cyanide and its radical cation, both of which are stable and did not undergo unimolecular rearrangement under the reaction conditions. The [C,N2,S] ions were characterized by mass spectrometry (ml% 72) (see Section 10.05.3.2.2) <1997JST(418)209>. 

Fortunately, the —NS ligand has received only one name, thionitrosyl, which is used here. A radical name, rather than an anionic name, is used which follows the precedent set by the nitrosyl ligand itself.
