Abstract
Seven new cobalt(III) complexes containing N-methylbis(2-aminoethyl)amine (4-methyldiethylenetriamine, abbreviated as dema) were prepared and their structures were determined by electronic, circular dichroism, and PMR spectroscopy. For the mixed [Co(dien) (dema)]3+ complex (dien=diethylenetriamine), three geometric isomers, s-fac, u-fac, and mer were isolated. The [Co(dema)2]3+ complex formed only s-fac isomer. A conformational analysis was carried out to compare the stability of these geometric isomers.This publication has 13 references indexed in Scilit:
