Abstract

The reaction of Mn(OAc)₂·4H₂O with 2,6-dimethoxybenzoylsalicylhydrazide (H₃dmbshz) leads to a dodecanuclear manganese metallamacrocycle [Mn₁₂(dmbshz) ₁₂(EtOH)₆], 1. The successive manganese centers are connected by the hydrazide N-N groups of the ligands in an alternating pentadentate binding mode, hexadentate binding mode. The alternation results in two alternating chelation modes around the metal centers, a tridentate- tridentate chelation mode and a bidentate-tridentate chelation mode. The metal ions in 1 are in a ⋯(A_AΔ_BC _AΛ_B)(A_AΔ_BC _AΛ_B)⋯ chiral sequence, the alternation of the chiralities expanding the cyclic ring system to a 36-membered dodecanuclear manganese metallamacrocyclic ring system with S₆ point group symmetry.
