“…Metal-organic frameworks (MOFs) have for decades been the center of unrelenting attentiona mong solid-state and materials chemists duet ot he immense possibilities for the application of such materials in numerous and diverse fields including photoluminescence, catalysis, gas absorption, drug transfer, electronics, and magnetism. [1][2][3][4][5] The structure and properties of MOFsc an be modified by variousf actorss uch as ligand structure, [6] coordination geometry of the metalc enter, [7] counter ions, [8] and experimental conditions. [9] Amongt he most exciting is the possibility of supramolecular control of the structure of MOFs, for example, through hydrogen bonding.…”

Three solid materials, [Pb(HL)(SCN)2 ]⋅CH3 OH (1), [Pb(HL)(SCN)2 ] (2), and [Pb(L)(SCN)]n (3), were obtained from Pb(SCN)2 and an unsymmetrical bis-pyridyl hydrazone ligand that can act both as a bridging and as a chelating ligand. In all three the lead center is hemidirectionally coordinated and is thus sterically optimal for participation in tetrel bonding. In the crystal structures of all three compounds, the lead atoms participate in short contacts with thiocyanate sulfur or nitrogen atoms. These contacts are shorter than the sums of the van der Waals radii (3.04-3.47 Å for Pb⋅⋅⋅S and 3.54 Å for Pb⋅⋅⋅N) and interconnect the covalently bonded units (monomers, dimers, and 2D polymers) into supramolecular assemblies (chains and 3D structures). DFT calculations showed these contacts to be tetrel bonds of considerable energy (6.5-10.5 kcal mol(-1) for Pb⋅⋅⋅S and 16.5 kcal mol(-1) for Pb⋅⋅⋅N). A survey of structures in the CSD showed that similar contacts often appear in crystals of Pb(II) complexes with regular geometries, which leads to the conclusion that tetrel bonding plays a significant role in the supramolecular chemistry of Pb(II) .

“…The ligand L was synthesized by the previously reported literature procedure. [34] IR spectra using KBr pellets were recorded on a Varian Fourier-transform (FT)-IR 640 spectrometer in the range of 4000-500 cm À1 . The TGA curves of 1-4 were measured on a Pyris Diamond thermal analyser at a heating rate of 108C min À1 under an N 2 atmosphere.…”

Using a bis-pyridyl-bis-amide N,N 0 -di(3-pyridyl)succinamide (L) and two dicarboxylates as mixed ligands, four 2D copper(II) metalÀorganic networks, formulated as [Cu(1,, and [Cu(2,5-tdc)(L)]Á2H 2 O (4) (L ¼ N,N 0 -di(3-pyridyl)succinimide; 1,4-H 2 chdc ¼ 1,4-cyclohexanedicarboxylic acid; 2,5-H 2 tdc ¼ thiophen-2,5-dicarboxylic acid) have been hydrothermally synthesized under different pH conditions, and characterized by IR spectroscopy, thermogravimetric analysis, and single-crystal X-ray diffraction. Compound 1, formed at pH 5.4, contains two rare types of left-, right-handed [Cu-L] n helix chains, which are further connected by [Cu-1,4-chdc] n zigzag chains, affording a 2D wave-like polymeric network. Compound 2 was obtained at pH 5.9, and shows a 2D square-grid layer constructed from zigzag [Cu-L] n chains and linear [Cu-1,4-chdc] n chains. Compounds 3 and 4 possess a similar 2D grid layer to that of 2 with 4 4 -sql topology, formed at pH 4.8 and 5.4 respectively, and are constructed from zigzag [Cu-L] n chains and linear [Cu-2,5-tdc] n chains. The effects of pH and secondary dicarboxylates on the diversity of structures are discussed. In addition, the thermal stabilities, photoluminescence properties, and photocatalytic activity of compounds 1-4 were also studied.
