The multidentate ligands (o-X·C6H4·Y·CH2)2(X = NH2, Y = O:ON; X = NH2, Y = S:SN; X = NH2, Y = NH:NN; X = Ph2As, Y = O:OAS; X = Ph2As, Y = S:SAS) and (Y = O:ONO; Y = S:NNO; Y = NH:NNO) have been prepared. Comparison of the complexes of cobalt(III), of the types [CoCl2(chelate)]+(chelate = ON, SN, and NN) and [Co(chelate)]+(chelate = ONO, SNO, and NNO) shows that the ligand field strength of the ether-oxygen
