2-溴-1,3,5-苯三甲酸 | 2-bromobenzene-1,3,5-tricarboxylic acid | 13520-03-1 | C9H5BrO6 | 289.039 |
The achiral 1,1'-biphenyl-2,2',6,6'-tetracarboxylic acid as well as its 4,4'-dibromo and 4,4'-dinitro derivative self-assemble in crystal under formation of a two-dimensional grid set up from hydrogen-bonded cyclotetrameric compartments which are individually chiral (D4 symmetry). The roughly square cavities (
