“…All the structures are constituted of cationic 1D chains of [Ni(H 2 O) 4 (L)] n 2+ and dianionic diphosphinate moieties. This arrangement, formed by a 1D string of metal, water, and bis-pyridine intercalated by another anionic ligand, is relatively common in the literature, and most of the reported structures were obtained as side products in the attempt to synthesize 3D networks. − The three compounds reported here are not isostructural, and the space groups are different, as reported in Table . The calculated density for 1 (1.547 g/dm 3 ) is larger than those of 2 (1.421 g/dm 3 ) and 3 (1.415 g/dm 3 ).…”

Three 1D nickel coordination polymers (CPs) based on P,P'-diphenylethylenediphosphinic acid and three different bis-pyridine co-ligands, namely 4,4'-bipyridine (bipy), 1,2-bis(4-pyridyl)ethane (bpyane) and 1,2-bis(4-pyridyl)ethane (bpy-ene), were prepared in mild hydrothermal conditions from water solutions containing the dissolved reagents. The CPs have formula [Ni(H2O)4(bipy)•pc2p]n (1),[Ni(H2O)4(bpy-ane)•pc2p]n (2), and [Ni(H2O)4(bpy-ene)•pc2p]n (3) and their structures were characterized by single crystal X-ray diffraction. They are constituted of infinite Ni(H2O)4(bis-pyridine) 1D rows connected, through hydrogen bonds, with the phosphinic acids placed among adjacent rows. Although the formulas and the structural topologies of the three compounds are almost identical, they behave in different manners upon heating. Compound 1 yields an amorphous phase when water molecules are thermally removed, whereas compound 3 undergoes interesting phase transformations derived from the connection of Ni atoms with the phosphinates oxygen atoms, increasing the dimensionality to 3D and maintaining crystallinity. The behavior of compound 2 has some analogies to that of 3 although a complete structural characterization was not performed because of a significant crystallinity loss of the heated phase. The structural features were studied by means of combination of variable temperature (VT) single crystal and powder X-ray diffraction and thermogravimetric analysis.

Due to their large surface areas, high pore volumes, relatively even distributions of pore sizes, surfaces enriched with unsaturated groups and orderly long-range structures, the mesoporous materials have been widely applied in industries such as chemical, biomedical, environmental protection and functional materials. In recent years, many scientists have demonstrated that the mesoporous molecular sieves have better adsorption of dyes in wastewater. This paper reviews the applications of different types of mesoporous adsorbents for removal of dyes in wastewater. It also presents the challenges and prospects in using the mesoporous materials for dye removal in wastewater treatment.
