1-Bromopyrrolidine-2,5-dione (cas: 128-08-5) belongs to organobromine compounds. Most of the natural organobromine compounds are produced by marine organisms, and several brominated metabolites with antibacterial, antitumor, antiviral, and antifungal activity have been isolated from seaweed, sponges, corals, molluscs, and others. The reactivity of organobromine compounds resembles but is intermediate between the reactivity of organochlorine and organoiodine compounds. For many applications, organobromides represent a compromise of reactivity and cost.Formula: C4H4BrNO2

Co-operative halogen bonds and nonconventional sp-C-H·O hydrogen bonds in 1:1 cocrystals formed between diethynylpyridines and N-halosuccinimides was written by Bosch, Eric;Bowling, Nathan P.. And the article was included in Acta Crystallographica, Section C: Structural Chemistry in 2022.Formula: C4H4BrNO2 This article mentions the following:

The rapid evaporation of 1:1 solutions of diethynylpyridines and N-halosuccinimides, that react together to form haloalkynes, led to the isolation of unreacted 1:1 cocrystals of the two components. The 1:1 cocrystal formed between 2,6-diethynylpyridine and N-iodosuccinimide (C4H4INO2·C9H5N) contains an N-iodosuccinimide-pyridine I·N halogen bond and two terminal alkyne-succinimide carbonyl C-HO hydrogen bonds. The three-dimensional extended structure features interwoven double-stranded supramol. polymers that are interconnected through halogen bonds. The cocrystal formed between 3,5-diethynylpyridine and N-iodosuccinimide (C4H4INO2.C9H5N) also features an I·N halogen bond and two C-H·O hydrogen bonds. However, the components form essentially planar double-stranded one-dimensional zigzag supramol. polymers. The cocrystal formed between 3,5-diethynylpyridine and N-bromosuccinimide (C4H4BrNO2.C9H5N) is isomorphous to the cocrystal formed between 3,5-diethynylpyridine and N-iodosuccinimide, with a Br·N halogen bond instead of an I·N halogen bond. In the experiment, the researchers used many compounds, for example, 1-Bromopyrrolidine-2,5-dione (cas: 128-08-5Formula: C4H4BrNO2).
