Two nickel(II) coordination polymers, formulated as {[Ni 2 (bix) 2 (tbta) 2 (H 2 O) 4 ] · 0.25H 2 O} n ( 1 ) and [Ni 2 (bix)(aip) 2 (H 2 O) 2 ] n ( 2 ) [bix = 1, 4‐bis(imidazol‐1‐ylmethyl)benzene, H 2 tbta = tetrabromoterephthalic acid, H 2 aip = 5‐aminoisophthalic acid] were synthesized under hydrothermal conditions and structurally characterized by single‐crystal X‐ray diffraction methods, IR spectroscopy, TGA, and elemental analysis. Complex 1 exhibits a 2D (4, 4) layer with {4 4 .6 2 } topology. Complex 2 shows 2D (3, 4)‐connected 3 , 4L83 sheets, which are finally extended into an unusual (5, 6)‐connected 3D supramolecular network by classic hydrogen bond interactions. Fluorescence, UV/Vis diffuse reflection spectra, and catalytic properties of two complexes for the degradation of the methyl orange dye in a photo‐Fenton‐like process were investigated.
