Abstract:
Two macrocyclic hexanuclear azaMetallacrowns, [Mn-6(II)(ahz)(6)(MeOH)(6)](.)6MeOH (1) and [Mn-6(III)(ashz)(6) (DMF)(6)](.)3DMF (2), were prepared using a trianionic pentadentate ligand N-acylsalicylhydrazide (ashz(3-)). The crystal data are trigonal R (3) over bar, a = b = 24. 806(2), c = 11. 260(1)Angstrom, Z = 3, mu = 1.007mm(-1), R = 0.0572, wR = 0.1142 for complex 1 and trigonal R (3) over bar, a = b = 26. 629(3), c = 23.298(4) Angstrom, Z = 6, mu = 0. 856 mm(-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 C-3i symmetry. The triple-deprotonated ligand ashz(3-) 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 similar to 275K) study indicates that there is an antiferromagnetic exchange interaction in the title compound 1. CCDC: 192835(complex 1); 192836(complex 2).
