Abstract The research investigations aiming at taking advantage of the chemical and structural consequences of ligand macrocyclization are reviewed with regard to the three features as follows: (1) Tetraazacycloalkane complexes which take up carbon dioxide as ROCO2 − or R2NCO2 −; (2) Correlation between axial and inplane coordination bond lengths in tetragonal six-coordinate complexes of trans-MX2N4-type (MyCo3+, Ni2+, and Zn2+)-X-ray structural and ab initio MO studies and (3) Stabilization of high oxidation states of metal ions and its application to chemistry of one-dimensional halogen-bridged M2+-M4+ mixed valence complexes.

Abstract Several cobalt(III) complexes incorporating 2,2′-diaminobiphenyl(dabp) and other 2(2N)- or 4N-type ligands were prepared and resolved by chemical and chromatographic methods: (1) [Co(en)2(dabp)]Cl22H2O, (2) [Co(l-pn)2(dabp)] (ClO4)34H2O, (3) [Co(l-chxn)2(dabp)](ClO4)33H2O, (4) α-[Co(trien)(dabp)](ClO4)3, (5) α-[Co(2S,9S-dimetrien)(dabp)] (ClO4)3 2H2O, (6) α-[Co(3S,8S-dimetrien)(dabp)] (ClO4)33H2O, (7 [Co(tren)(dabp)]Cl35H2O, (8) [Co(bpy)2(dabp)] Cl33H2O. The complexes (1), (4) and (8) gave one pair of enantiomers, Δ(Λ) and Λ(δ), and the complexes (2) and (3) gave only one Δ-isomer. The absolute configuration of the complexes (5) and (6) was found to be Λ, and that of (7) was not determined because of unsuccessful resolution. The three geometric isomers of the complex (2) were separated and their structures assigned.
