PRASAD, R N.  y  GUPTA, SEEMA. TEMPLATE SYNTHESIS OF 2,11-DIMETHYL-3,12-DIETHYL / PROPYL / PHENYL-1,4,10,13-TETRAAZACYCLOOCTADECA-1,3,10,12-TETRAENE COMPLEXES OF Mg(II), Ca(II), Sr(II) AND Ba(II). J. Chil. Chem. Soc. [online]. 2004, vol.49, n.1, pp. 25-29. ISSN 0717-9707.  http://dx.doi.org/10.4067/S0717-97072004000100005.

2+2 Cyclocondensation of 1,5-diaminopentane with b-diketones viz. 2,3-pentanedione, 2,3- hexanedione or 1-phenyl -1,2- propanedione in the presence of alkaline earth metal ions as templates yield a series of hexacoordinated complexes of the type [ML(X2)] ( where L=N4 macrocyle having 18-membered ring and X = Cl or NCS) The resulting complexes have been characterized by elemental analyses, conductance measurements, IR and 1H NMR spectra
