Abstract
The crystal structure of ethylenediamine dihydrochloride has been determined by the two-dimensional Patterson methods and refined by two-dimensional Fourier syntheses. The unit cell dimensions are a = 4.440.02, b = 6.880.02, c = 9.970.02 , = 92. The space group is . The carbon and nitrogen atoms in the ethylenediamine itself lie on one plane and its structure has a trans-form with a centre of symmetry in it, and C-C distance of 1.54 , C-N distance of 1.48 and C-C-N bond angle of . The molecules are linked by N-HCl hydrogen bonds with distance of 3.14, 3.16 and 3.22 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.
