Trimethylenediamine dihydrochloride, H2N(CH2)3NH2.2HCl, crystallizes in the orthorhombic system with a = 8.53, b = 9.36, c = 9.40 A., and space group Pbcn. The structure was determined by using the 3-dimensional Fourier function, and anisotropic refinement of the structure was carried out by using the least-sqs. method. The trimethylene-diammonium ion possesses a 2-fold axis included in the mol. plane, which passes through the central C atom. The ion is not coplanar; both the N atoms depart from the mol. plane by 0.128 A. Three N-H…Cl hydrogen bonds make a 3-dimensional network as in similar structures.
