Description

The cobalt(III) complexes, [Co(acac)2(amine)2]X, have been reported for a variety of amines and counter ions, X. While synthesizing a series of thiocyanato complexes, two complexes, [Co(acac)2(pyr)2]SCN and (Co(acac)2(4-Mepyr)2]SCN, were observed to undergo a reaction (Equation 1) forming green products in chloroform and acetic acid solution. These products have been characterized as [Co(acac)2(amine)2]2Co(NCS)4, which contain paramagnetic Co(II) and diamagnetic Co(m) moieties.
