Abstract
Template condensation reactions between the dinuclear nickel(II) or copper(n) complexes of the hexaaza macrocycles 1,4,7,9,12,15-hexaaza-8,8,16,16-tetrachlorocyclohexadecane (HTCH) or 1,4,7,10,13,16-hexaaza-8,9,17,18-tetrachlorocyclooctadecane (HTCO) and triethylenetetramine have yielded products of three new macrocyclic ring systems : 1,4,7,10,12,15,18,20,23,26,29,30,33,36-tetradecaazadispiro[10.7.10.7]hexatriacontane (TDSH), 2,5,8,11,14,17,19,22,25,28-decaaza-9,10-dichlorobicyclo[16.10.0]octacosane (DDCO) and 2,5,8,10,13,16,19,21,24,27,29,32,35,38-tetradecaazatricyclo[26.10.0.0 9,20 ]octatriacontane (TTCO). Formulation of these products as [Ni 4 (TDSH)(H 2 O) 10 ]Cl 8 .5H 2 O, [Cu 4 (TDSH)-(H 2 O) 2 ]Cl 8 , [Ni 3 (DDCO)(H 2 O) 8 ]Cl 6 and [Ni 4 (TTCO)(H 2 O) 10 ]Clg and the metal-free TDSH.14HCl has been supported by elemental analyses, conductivity measurements, melting points and spectroscopic studies.
