Abstract	The crystal structure of ethylenediamine dihydrochloride has been determined by the methods and refined by two-dimensional Fourier syntheses. The unit cell dimensions are a = 4.44±0.02, b = 6.88±0.02, c = 9.97±0.02 Å, β = 92±1°. The space group is P21/c. The carbon and nitrogen atoms in the ethylenediamine itself lie on one and its structure has a trans-form with a centre of symmetry in it, and C-C distance of 1.54 Å, C-N distance of 1.48Å and C-C-N bond angle of 109.07°. The molecules are linked by N-H…Cl hydrogen bonds with distance of 3.14, 3.16 and 3.22 Å forming three dimensional network. The values of reliability factor for F(okl), F(hol) and F(hko) are 0.11, 0.10 and 0.09 respectively.
