An organic ammonium salt [(Cl-C7H4 O2) 2] · (C2 H1 0 N2) was synthesized and its structure was characterized by elemental analysis and X-ray diffractometry. The results showed that the crystal was monoclinic Crystal system, space group C2 / c. Each repeating unit consists of two 4-chlorobenzoate anions and one ethylenediamine cation. Hydrogen bonds between the nitrogen and oxygen atoms link the compound molecules along the c-axis Form a one-dimensional chain, one-dimensional chain through Cl ... Cl weak interaction (Cl ... Cl = 0.33303 (0.3) nm) along the ac plane to form a two-dimensional spatial network structure.
