“…y, z; b 1D double chain of 1; c 3D framework with a two-nodal (4, 4)-connected bbf topology knowledge, the cds network based on ligand L2 has not previously been reported. A structure reported in the literature, {[Co(L1)(ip)]ÁH 2 O} n (3) [20], provides an interesting point of comparison. Both bis(benzimidazole) ligands (L1 and L2) contain a semirigid -(Ph-CH 2 )-spacer and two freely twisting benzimidazole arms.…”

Two new metal-organic coordination polymers {[Co(L1)(nip)]ÁH 2 O} n (1) and [Co(L2)(ip)] n (2) (H 2 ip = isophthalic acid, L1 = 1,3-bis(benzimidazol-1-ylmethyl) benzene, L2 = 1,4-bis(5-methylbenzimidazol-1-ylmethyl) benzene, H 2 nip = 5-nitroisophthalic acid) have been synthesized under hydrothermal conditions and characterized by physicochemical and spectroscopic methods as well as single-crystal X-ray diffraction analysis. The analysis reveals that complex 1 has a 1D double chain structure connected by L1 and nip 2-ligands, which is further assembled into a 3D bbf (moganite network) supermolecular framework via two types of C-HÁÁÁO hydrogen bond interactions. Complex 2 possesses a 3D MOF with a fourconnected cds (CdSO 4 network) topology. The fluorescence and catalytic properties of the complexes for the degradation of Congo red have been investigated.

“…However, the controllable synthesis of these complexes with desired architectures and properties is still a great challenge, which is because a lot of factors show significant effect on this framework, such as the nature of organic ligands, pH, central metal ion, temperature, solvents etc. [5][6][7][8]. Moreover, the selection of appropriate organic ligands is the key point in manipulating the structures of the coordination polymers [ 9 ].…”

A new Zn(II) coordination polymer, {[Zn(npht)(L) 0.5 (H 2 O)]H 2 O} n (L = 1,4-bis(2-methylbenzimidazol-1-ylmethyl)benzene, H 2 npht = 3-nitrophthalic acid) has been hydrothermally synthesized and characterized by elemental analysis, IR, XRPD, and single-crystal X-ray diffraction. The Zinc(II) coordination compound exhibits a 1D linear chain, which is further assembled into a 2D supramolecular layer via two modes of classial hydrogen bonding interactions. The fluorescence properties and thermal stability of the complex have been investigated in the solid state.
