The crystal structure of some molecular complexes of 4:4'-dinitrodiphenyl II. The complexes with benzidine, NN : N'N' -tetramethylbenzidine, 4:4'-dihydroxydiphenyl, 4-iododiphenyl and 4-bromodiphenyl

Approximate structures are described for the complexes of 4 :4'-dinitrodiphenyl with benzidine,N N :N'N' -tetramethylbenzidine, 4:4'-dihydroxydiphenyl, 4-iododiphenyl and 4-bromodiphenyl. A comparison of the more important spectra, of the diffuse reflexions due to thermal vibrations, of the cell dimensions and of photographs taken about structurally equivalent directions, leads to the conclusion that these structures are all of the same general type, and are closely similar to the structure of the complex between 4:4'-dinitrodiphenyl and 4-hydroxydiphenyl, described in detail in part I.
