Description:
Abstract. Based on a mononuclear precursor [Mn(Hstp) 2 (4,4′-Hbpy) 2 ] ( 1 ), a hetero-metallic complex, [Mn 2 Ni(stp) 2 (4,4′-bpy)(H 2 O) 4 ] ( 2 ) [stp = 2-sulfoterephthalate, 4,4′-bpy = 4,4′-bpyridine] was synthesized by solvothermal reaction. Single-crystal X-ray diffraction analysis reveals that the Mn II ion of the precursor 1 is hexacoordinate by four oxygen atoms from two Hstp 2– anions and two nitrogen atoms from two protonated 4,4′-Hbpy, and hydrogen bonding plays a significant role in constructing 3D supramolecular structure. While complex 2 features a self-weaving framework from 1D straight chains and 2D wavy networks with double helical chains. Magnetic behavior of complex 2 was analyzed in connection with its crystal structure, which exhibits the weak antiferromagnetic interactions between the Mn II and Ni II ions.
