Wagner, Pawel published the artcileCrystal packing of two 5-substituted 2-methyl-4-nitro-1H-imidazoles, Safety of 5-Bromo-2-methyl-4-nitroimidazole, the main research area is crystal packing methyl nitro imidazole derivative; mol structure bromomethylnitroimidazole methylnitroimidazolecarbonitrile; structure crystal bromomethylnitroimidazole methylnitroimidazolecarbonitrile; hydrogen bond bromomethylnitroimidazole methylnitroimidazolecarbonitrile.
Infinite chains connected by N-H···N H bonding form the primary packing motif in two closely related 4-nitroimidazole derivatives, viz. 5-bromo-2-methyl-4-nitro-1H-imidazole, C4H4BrN3O2, (I), and 2-methyl-4-nitro-1H-imidazole-5-carbonitrile, C5H4N4O2, (II). These chains are almost identical, even though in (II) there are two symmetry-independent mols. in the asym. unit. The differences appear in the interactions between the chains; in (I), there are strong C-Br···O halogen bonds, which connect the chains into a two-dimensional grid, while in (II), the cyano group does not participate in specific interactions and the chains are only loosely connected into a three-dimensional structure. Crystallog. data are given.
Acta Crystallographica, Section C: Crystal Structure Communications published new progress about Crystal structure. 18874-52-7 belongs to class imidazoles-derivatives, name is 5-Bromo-2-methyl-4-nitroimidazole, and the molecular formula is C4H4BrN3O2, Safety of 5-Bromo-2-methyl-4-nitroimidazole.
