Abstract: On the basis of triangular-shaped [Mn3O] secondary building units, a novel two-dimensional (2D) manganese(III) complex, [NaMnIII 3O(sao)3(btec)0.5(H2O)3]·1.25H2O (1) (H2sao=salicylaldoxime, H4btec=benzene-1,2,4,5-tetracarboxylate acid), was synthesized and structurally characterized. The structure of 1 consists of 2D coordination polymer based on [Mn3O] units bridged by sodium ions and benzene-1,2,4,5-tetracarboxylate groups. Magnetic data analysis shows that antiferromagnetic couplings exist between the manganese(III) ions in [Mn3O] subunit of complex 1. [Copyright &y& Elsevier]

Abstract: On the basis of triangular-shaped secondary building units, a hexanuclear manganese(III) complex, [MnIII 6O2(sao)6(N3)2(H2O)8]·2.5H2O (1) (H2sao=salicylaldoxime), was synthesized and structurally characterized. The structure of 1 consists of two triangular-shaped [Mn3O] connected with end-to-end (EE) azide group. Magnetic data analysis shows that antiferromagnetic couplings dominated in the complex.
