Abstract A new coordination network based on 5-(1H-benzoimidazol-2-ylsulfanylmethyl)-isophthalic acid (H2bismip) along with 4,4-bis(1-imidazolyl)bibenzene (bimb), formulated as [Ni2(bismip)2(bimb)2(H2O)]n (1) has been synthesized under solvothermal condition. Compound 1 has been structurally characterized by elemental analysis, IR spectroscopy, powder X-ray diffraction (PXRD). Single crystal X-ray diffraction analysis shows compound 1 is a 2D network with a Schlafli symbol of 44. The layer framework exhibits effective adsorption on organic dye. The kinetic of the adsorption process was analyzed by the pseudo-first-order and pseudo-second-order model equations and the data was fitted well with the pseudo-second-order kinetic model (R > 0.99). The compound was found to be an excellent selective absorbent for the removal of methyl orange (MO) from the mixture solution of methyl orange - methylene blue (MO-MB).
