“…The free ligand bib displays photoluminescence with emission maxima at 400 nm (λ ex = 330 nm), assigned to π* → π transition of bib [27,28]. The carboxylate ligands display photoluminescence with emission maxima 470 nm (λ ex = 340 nm) for H 2 atibdc, 469 nm (λ ex = 340 nm) for H 2 atbip, 330 nm (λ ex = 300 nm) for 2,2′-H 2 tda, and 510 nm (λ ex = 340 nm) for 5-H 2 tbipa [29][30][31][32]. The emission bands of these carboxylate ligands can be assigned to the π* → n transition as previously reported [33].…”

Solvothermal reactions of Zn(II) acetates and four V-shaped carboxylates ligands in the presence of 1,4-Bis(2-methyl-imidazol-1-yl)butane afforded four interesting Zn(II) coordination polymers with helical chains, namely, {[Zn(bib)(atibdc)]•2H 2 O} n (1), {[Zn(bib)(atbip)]•H 2 O} n (2), [Zn(bib)(2,2′-tda)]} n (3) and {[Zn(bib)(5-tbipa)]•EtOH} n (4), (H 2 atibdc = 5-amino-2,4,6-triiodoisophthalic acid, H 2 atbip = 5-amino-2,4,6-tribromoisophthalic acid, 2,2′-H 2 tad = 2,2′-thiodiacetic acid, 5-H 2 tbipa = 5-tert-butyl-isophthalic acid). 1 reveals a 3D chiral framework with three kinds of helical chains along a, b and c axis. 2 shows a 2D step-type chiral framework with right-handed helical chains. 3 displays a wavelike 2D layer network possessing alternate left-and right-handed helical chains. 4 presents a four-connected 3D framework with zigzag and meso-helical chains. The different spacers and substituent group of carboxylic acid ligands may lead to the diverse network structures of 1-4. The fluorescent properties of complexes 1−4 were studied. In addition, the thermal decompositions properties of 1−4 were investigated by simultaneous TG/DTG−DSC technique. The apparent activation energy E and the pre-exponential factor (A) of skeleton collapse for the complexes 1−4 are calculated by the integral Kissinger's method and Ozawa−Doyle's method. The activation energy E (E 1 =209.658 kJ•mol-1 , E 2 =250.037 kJ•mol-1 , E 3 =225.300 kJ•mol-1 , E 4 =186.529 kJ•mol-1) demonstrates that the reaction rate of the melting

“…However, the coordination chemistry of lead is a fascinating area as it has a tendency to form polynuclear metal compounds (Aijaz et al, 2011;Davidovich et al, 2009). Up to now, a few well defined cluster-type motifs have been reported, including Pb 2 , Pb 4 , Pb 6 , Pb 7 , Pb 8 , Pb 10 , Pb 14 and Pb 16 clusters (Aslani & Morsali, 2008;Cai et al, 2012;Li et al, 2006;Li, Zhang et al, 2012;Oldag & Keller, 2006;Shieh et al, 2011;Zhang et al, 2012).…”

Reactions of 2-(hydroxymethyl)pyridine (Hhmp) with PbCl2 and Pb(NO3)2 at room temperature led to the formation of two novel compounds, namely tetrakis[μ3-(pyridin-2-yl)methanolato]-tetrahedro-tetrakis[chloridolead(II)], [Pb4(C6H6NO)4Cl4], (I), and poly[(μ2-nitrato)[μ2-(pyridin-2-yl)methanolato]lead(II)], [Pb(C6H6NO)(NO3)]n, (II). Compound (I) exhibits a tetranuclear Pb4O4 cubane structure, which is connected through π-π stacking interactions between the pyridine groups of the (pyridin-2-yl)methanolate (hmp(-)) ligands and through C-H···Cl interactions to form an interesting threefold diamondoid network. Compound (II) possesses two-dimensional (4,4)-sql topology based on a Pb2O2 unit, which is further extended into a three-dimensional supramolecular network through π-π stacking interactions between adjacent pyridine rings and through C-H···O interactions between the pyridine C atoms of the hmp(-) ligands and the nitrate anions.

“…Considering that halogen atoms (Br/I) on an aromatic ring can act as halogen-bond sites and an amino group can play the role of a hydrogen-bond donor, making it easy to form highdimensional supramolecular networks, we have chosen multifunctional 5-amino-2,4,6-triiodo(bromo)isophthalic acids (H 2 ATIBDC or H 2 ATBIP) to construct coordination polymers with potentially interesting architectures and properties (Zhang et al, 2010(Zhang et al, , 2012. Herein, we selected H 2 ATBIP as the research papers linker to assemble with Zn II ions, incorporating N-donor bipyridyl-type ligands with different backbones between the two pyridin-4-yl rings, i.e.…”

The bromo‐substituted aromatic dicarboxylic acid 5‐amino‐2,4,6‐tribromoisophthalic acid (H2ATBIP), in the presence of the N‐donor flexible bipyridyl‐type ligands 1,3‐bis(pyridin‐4‐yl)propane (bpp) and N,N′‐bis(pyridin‐4‐ylmethyl)oxalamide (4‐bpme) and ZnII ions, was used as an O‐donor ligand to assemble two novel luminescent metal–organic frameworks (MOFs), namely poly[[(μ‐5‐amino‐2,4,6‐tribromoisophthalato‐κ2O1:O3)[μ‐1,3‐bis(pyridin‐4‐yl)propane‐κ2N:N′]zinc(II)] dimethylformamide monosolvate], {[Zn(C8H2Br3NO4)(C13H14N2)]·C3H7NO}n, (1), and poly[[(μ‐5‐amino‐2,4,6‐tribromoisophthalato‐κ2O1:O3)diaqua[μ‐N,N′‐bis(pyridin‐4‐ylmethyl)oxalamide‐κ2N:N′]zinc(II)] monohydrate], {[Zn(C8H2Br3NO4)(C14H14N4O2)(H2O)2]·H2O}n, (2), using the solution evaporation method. Both (1) and (2) were characterized by FT–IR spectroscopy, elemental analysis (EA), solid‐state diffuse‐reflectance UV–Vis spectroscopy, and powder and single‐crystal X‐ray diffraction analysis. Complex (1) shows a two‐dimensional (2D) corrugated layer simplified as a 2D (4,4) topological network. The supramolecular interactions (π–π stacking, hydrogen bonding and C—Br…Br halogen bonding) play significant roles in the formation of an extended three‐dimensional (3D) supramolecular network of (1). Complex (2) crystallizes in the chiral space group P212121 and exhibits a novel 3D homochiral framework, showing a diamond‐like topology with Schläfli symbol 66. The homochirality of (2) is further confirmed by the solid‐state circular dichroism (CD) spectrum. The second harmonic generation (SHG) property of (2) was also investigated. The hydrogen and C—Br…Br/O halogen bonding further stabilize the framework of (2). The central ZnII ions in (1) and (2) show tetrahedral and octahedral coordination geometries, respectively. The coordinated and uncoordinated water molecules in (2) could be removed selectively upon heating. Most importantly, (1) and (2) show rapid and highly sensitive sensing for a large pool of nitroaromatic explosives (NAEs).
