A new supramolecular net constructed with 2D (4,4) layer subunits displaying unique 4-connected msw/P42/nnm topology: Structure, fluorescence and catalytic properties

A new three-dimensional supramolecular framework based on 1,4-bis(5,6-dimethylbenzimidazole)butane (L) with 5-hydroxyisophthalic acid (H2hip) has been synthesized by hydrothermal reaction, namely, [Co(L)0.5(hip)]n, exhibiting an unprecedented topology architecture through hydrogen bonds, viz. supramolecular net 4-connected uninodal 3D net with (65⋅8) msw/P42/nnm topology. The fluorescence and remarkable catalytic performances of the complex for the degradation of methyl orange by sodium persulfate have been investigated.
