Resumen de 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)

• 2+2 Cyclocondensation of 1,5-diaminopentane with beta-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
