A hexanuclear manganese(III) complex constructed from triangular-shaped [Mn_3O] units with azide bridge

摘要

On the basis of triangular-shaped secondary building units, a hexanuclear manganese(III) complex, [Mn~III_6O_2(sao) _6(N_3)_2(H_2O)_8]·2. 5H_2O (1) (H_2sao = salicylaldoxime), was synthesized and structurally characterized. The structure of 1 consists of two triangular-shaped [Mn_3O] connected with end-to-end (EE) azide group. Magnetic data analysis shows that antiferromagnetic couplings dominated in the complex.
