Abstract

New cobalt (III) complexes of the types, trans-[CoCl 2 L 2]+,[Co (NH 3) 4 L] 3+, cis-[Co (NH 3) 2 L 2] 3+, and [Co (en) 2 L] 3+, where L denotes a seven-membered chelate diamine ligand,(R)-2-methyl-1, 4-butanediamine or meso-and (R or S)-2, 5-hexanediamine, have been prepared. The dichloro complexes decompose gradually even in the solid state, and rapidly in methanol. The ammine and ethylenediamine complexes are stable in acidic ...
