Abstract

Two helical one-dimensional complexes [MnII(MeOH)4][MnIV(L·)2]·2MeOH (1) and [MnIII(salen)][MnIII(L)2] (2) (H2L = HON=C(Ph)N=NC6H4CO2H) contain the noninnocent ligand [Mn(L·)2]2− and innocent low-spin [Mn(L)2]−. Intrachain antiferromagnetic interaction between adjacent manganese ions via the syn-anti carboxylate bridges in complex 1. Alternate syn-anti and anti-anti carboxylate bridges have been found to transmit ferro- and antiferromagnetic coupling between high-spin and low-spin Mn(III) ions in complex 2.
