Structural and spectroscopic characterization of N,N′-bis(2-pyridylmethyl)-ethylenediamine tetrahydrochloride dihydrate

The crystal structure of the title compound, [(C5H4NH)–CH2–NH2–(CH2)2–NH2–CH2(C5H4NH)]Cl4·2H2O, a potentially useful agent for chelation therapies, has been determined by single crystal X-ray diffractometry. It crystallizes in the monoclinic space group P21/c with Z = 2. The FT-IR and Raman spectra as well as the 1H and 13C NMR spectra of the compound were also recorded and briefly discussed.
