摘要
Two new Mn(II) coordination polymers, namely, [Mn(Haip)2(H2O)(2)] (1), and [Mn-2(aip)(2)(bpy)]center dot 3H(2)O (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 Schlafli symbol of (4.6(2))(4.6(7).8(2)), which is constructed from helical chains. Coordination modes of H(2)aip 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).
