Abstract
Nickel(II) and cobalt(II) complexes of the general compositions Mt Tpt acdte)X-2 (Tptacdte = nyl-1,4,7,10-tetraazacyclododeca-1,3,7,9-tetraen e; X = Ci, Br, SCN for Ni(ll) and X = Cl, NO,, SCN for Co(II) and Co(T ptacdte)SO4 .(H2O)(2) have been synthesized. The complexes have been c haracterized on the basis of elemental analyses, molar conductance mea surements, magnetic susceptibility measurements, IR and electronic spe ctral studies. The complexes were found to stabilize an octahedral geo metry for the Ni(II) complexes and a distorted octahedral geometry for the Co(II) complexes.
