Assembly of two new Mn(II) coordination polymers based on 5-aminoisophthalate : structural diversity and properties
Two new Mn(II) coordination polymers, namely, [Mn(Haip)2(H2O)2] (1), and [Mn2(aip)2(bpy)]·3H2O (2) were obtained under hydrothermal conditions (aip = 5-aminoisophthalate; bpy = 2, 2′-bipyridine). Compound 1 features a 1D loop-like chain structure, and complex 2 possesses an interesting (3, 5)-connec...

| Summary: | Two new Mn(II) coordination polymers, namely, [Mn(Haip)2(H2O)2] (1), and [Mn2(aip)2(bpy)]·3H2O (2) were obtained under hydrothermal conditions (aip = 5-aminoisophthalate; bpy = 2, 2′-bipyridine). Compound 1 features a 1D loop-like chain structure, and complex 2 possesses an interesting (3, 5)-connected 2-nodal 3D architecture with the Schläfli symbol of (4.62)(4.67.82), which is constructed from helical chains. Coordination modes of H2aip molecules and coligands have significant effect on the structures of the resulting complexes. Moreover, variable-temperature magnetic susceptibility measurement of complex 2 exhibits antiferromagnetic interactions between nearest Mn(II) ions with J = − 0.88(5) cm− 1 and g = 2.04(3). |
