Two mixed-ligand compounds,namely[Mn_(2)(bimb)(PA)_(2)]_(n)(1)and[Zn(bimb)(PA)]n(2)(H_(2)PA=pamoic acid,bimb=1,4-bis(imidazol-1-yl)-butane)have been synthesized under the same solvothermal conditions.Compound 1 can be...Two mixed-ligand compounds,namely[Mn_(2)(bimb)(PA)_(2)]_(n)(1)and[Zn(bimb)(PA)]n(2)(H_(2)PA=pamoic acid,bimb=1,4-bis(imidazol-1-yl)-butane)have been synthesized under the same solvothermal conditions.Compound 1 can be described as(4,4)topology based on the 4-connected[Mn_(2)(COO)_(4)]paddle-wheel units,which contains both rotaxane-and catenane-like motifs.For 2,the 2D wavy-like network interlocked with each other and resulted in a 2-fold interpenetrated 2D→3D architecture.The structural differences of the two compounds are mainly due to the differences of metal ions and coordination modes of the PA^(2-)ligand.In addition,the magnetism and photoluminescent properties of them have also been explored.展开更多
