| Abstract: | Abstract. Based on a mononuclear precursor Mn(Hstp)2(4,4′‐Hbpy)2] ( 1 ), a hetero‐metallic complex, Mn2Ni(stp)2(4,4′‐bpy)(H2O)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 MnII ion of the precursor 1 is hexacoordinate by four oxygen atoms from two Hstp2– 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 MnII and NiII ions. |
