Abstract
Hansagelb G has the structure formula N-Phenyl-2-(4-methyl-2-nitro-phenylhydrazono)-3-oxo-butyramide. Like other “azo”-pigments the molecule prefers – at least in solid state – the hydrazono – to the azo-tautomeric form. It crystallizes in the monoclinic space group P21/n with 4 molecules in the unit cell. It could be shown that the cell constants given in the literature are wrong. The molecules are crystallizing in layers built by endless tapes joined together like staircases.
