Nickel(II) and cobalt(II) complexes of the general compositions M( Tptacdte)X2 (Tptacdte = 2,3,8,9-tetraphenyl-1,4,7,10-tetraazacyclododeca-1,3,7,9-tetraene; X = Cl, Br, SCN for Ni(II) and X = Cl, NO3, SCN for Co(II) and Co(Tptacdte)SO4.(H2O)2 have been synthesized. The complexes have been characterized on the basis of elemental analyses, molar conductance measurements, magnetic susceptibility measurements, IR and electronic spectral studies. The complexes were found to stabilize an octahedral geometry for the Ni(II) complexes and a distorted octahedral geometry for the Co(II) complexes.

2 + 2 Cyclocondensation of benzil with aliphatic diamines viz. 1,2-diaminoethane, 1,3-diaminopropane, 1,4-diaminobutane, 1,6-diaminohexane, 1,8-diaminooctane or 1,12-diaminododecane in the presence of Co(II) as a template yields a series of pentacoordinated high spin Co(II) complexes of the type X (where L = N4 macrocycle having 12- to 32-membered ring and X = NO3, Cl).The complexes have been characterized by elemental analyses, IR and diffuse reflectance spectra, conductances and magnetic measurements. Key words: Tetraazamacrocycles, Cobalt(II) Complexes, Template Synthesis
