Crystal structure and Hirshfeld surface analysis of 1-carboxy-2-(3,4-dihydroxyphenyl)ethan-1-aminium bromide 2-ammonio-3-(3,4-dihydroxyphenyl)propanoate

Crystal structure and Hirshfeld surface analysis of 1-carboxy-2-(3,4-dihydroxyphenyl)ethan-1-aminium bromide 2-ammonio-3-(3,4-dihydroxyphenyl)propanoate

In the title molecular salt, C9H12NO4+·Br−·C9H11NO4, one of the dopa molecules is in the cationic form in which the α-amino group is protonated and the α-carboxylic acid group is uncharged, while the second dopa molecule is in the zwitterion form. The Br− anion occupies a special position and is loc...
