Abstract:

Two macrocyclic hexanuclear azaMetallacrowns, [MnIII 6(ashz)6(MeOH)6] · 6MeOH (1) and [MnIII6(ashz)6 (DMF)6] · 3DMF (2), were prepared using a trianionic pentadentate ligand N- acylsalicylhydrazide (ashz3-). The crystal data are trigonal R 3, a = b = 24.806(2), c = 11.260(1) Å, Z = 3, μ = 1.007mm-1, R = 0.0572, wR = 0.1142 for complex 1 and trigonal R3, a = b = 26.629(3), c = 23.298(4) Å, Z = 6, μ = 0.856mm-1, R = 0.0671, wR = 0.1661 for complex 2. They are of 18-azametallacrown-6 structure type. The metallacrown molecules in two title complexes have a crystallographic C3i symmetry. The triple-deprotonated ligand ashz3- in the title complexes bridges the metal ions by a hydrazide N-N group, forming a hexanuclear manganese metallmacrocycle with a cavity in the center. The magnetic susceptibility (4 ∼ 275K) study indicates that there is an antiferromagnetic exchange interaction in the title compound 1. CCDC: 192835 (complex 1); 192836 (complex 2).
