The Crystal Structure of Hexamethylenediamine dihydroiodide
Kwan-sub Han
Hexamethylenediamine dihydroiodide is monoclinic, with cell dimensions a=4.85Å, b=12.77Å, c=9.73Å, β=91.5° The space group is P21/c, with two molecules per unit cell. It has a center of symetry in the molecule. All atomic positions are determined by means of a two-dimensional patterson synthesis and fourier synthesis. The C-N bond distance is 1.48Å and the C-C bond distances are lying between 1.55Å, and 1.59Å. The iodine atom is bonded by hydrogen bridges of 3.59ű0.1Å to nitrogen atoms and surrounded by three nitrogen atoms. The hexamethylenediamine chain is zigzag in the hexamethylenediamine dihydrochloride molecules though, it is not zigzag in the hexamethylenediamine dihydroiodide.
