N-(2-Aminoethyl)-1,3-propanediamine has been used as a templating agent in the synthesis of a new open framework iron(III) phosphite {(C5H18N3)[Fe3(HPO3)6].3H2O}. It has also been used in the preparation of dinitrocobalt(III) compound: (11-amino-4-methyl-5,8-diazaundeca-2,4-dien-2-olato-kappa4N(5,8,11),O)-dinitrocobalt(III), [Co(C10H20N3O)(NO2)2].
