Abstract

The crystal and molecular structure of hexamethylene diamine and its dihalides have been investigated by X-ray diffraction methods. Atomic parameters have been completely refined by two-dimensional Fourier series, and in the case of the dihalides the structure analysis was immensely aided by two-dimensional Patterson series and also by the fact that they proved to be isomorphous. A technique has been developed for the detailed examination of hygroscopic hexamethylene diamine. An interesting complex lattice of halogen ions and nitrogen atoms is found in the dihalides, and they also provide bond lengths comparable with those of hexamethylene diamine. These bond lengths are reminiscent of a conjugated molecule. Resolution of the hydrogen atoms of hexamethylene diamine is observed in the Fourier projections, and so their contributions have been included in the calculated structure factors.
