| Abstract: | Starting from Ba2(1,3-pddadp)·8H2O (1,3-pddadp=1,3-propanediamine-N,N′-diacetate-N,N′-di-3-propionate ion) and CoSO4, a new hexadentate CoII(1,3-pddadp)]2− complex has been prepared. The trans(O6) geometry of this complex was confirmed by comparison of its i.r. and u.v.–vis. spectra with those of CoII(1,3-pdta)]2− (1,3-pdta is the 1,3-propanediaminetetraacetate ion) and trans(O6)-CoIII(1,3-pddadp)]− complexes of known X-ray crystal structure. Magnetic and electrolytic conductivity properties of these complexes have also been discussed. |
