“…Ligand ppvppa was prepared in two steps using modified literature procedures. , As shown in Scheme , the first step involved the CuI-catalyzed cross-coupling reaction of 1,4-diiodobenzene with dipyridylamine in refluxing DMF to give 4-(2,2′-dipyridylamino)-phenyl iodide as a white microcrystalline substance in about 60% yield. The 1 H NMR spectrum of 4-(2,2′-dipyridylamino)-phenyl iodide shows the multiplets at δ = 7.69 and 6.89 ppm, which are ascribed to the four protons of the phenyl group.…”

A stable two-dimensional (2D) coordination Cd(II) polymer [Cd(ppvppa)(1,4-NDC)] n (1) (ppvppa = N-(pyridin-2-yl)-N-(4-(2-(pyridin-4-yl)vinyl)phenyl)pyridin-2-amine; 1,4-H2NDC = 1,4-naphthalenedicarboxylic acid) was prepared by the solvothermal reactions of Cd(NO3)2·4H2O with ppvppa and 1,4-H2NDC in H2O and MeCN at 150 °C. Compound 1 was characterized by elemental analysis, IR, powder X-ray diffraction (PXRD), and single crystal X-ray diffraction and thermogravimetric analysis (TGA). Compound 1 consists of dimeric [Cd2(μ-ppvppa)2] fragments linked by 1,4-NDC bridges to generate a 2D honeycomb network. Complex 1 strongly emits blue light in the solid state when excited at 419 nm at ambient temperature. This emission is selectively quenched by nitro aromatic compounds in water with good sensitivity. Compound 1 also displays recyclable detection of nitro aromatic compounds.

“…The bis(dipyridylaminophenylethynyl)toluene ligand L was synthesized in two steps: the first step involved the reaction of 1,4-diiodobenzene with dipyridylamine in DMF under reflux and in the presence of CuI to give after reaction workup 4-(2,2′-Dipyridylamino)-phenyl iodide as a white microcrystalline substance in 87% yield . In a second step the latter was treated with 3,5-diethynyl-toluene following a Pd/Cu catalyzed Sonogashira coupling reaction to give the target tetradentate ligand 3,5-Bis[-(2,2′-dipyridylamino)phenylacetylenyl]toluene after reaction workup.…”

Meso-Helicates with Rigid Angular Tetradentate Ligand: Design, Molecular Structures, and Progress Towards Self-Assembly of Metal–Organic Nanotubes

The self-assembly of two novel metallosupramolecular complexes of the general formulas [L2M2(CH3CN)4][BF4]4 (M = Co, 1a; M = Ni, 1b), where L stands for the tetradentate ligand 3,5-bis[4-(2,2'-dipyridylamino)phenylacetylenyl]toluene, is reported together with their molecular structures ascertained by single-crystal X-ray diffraction studies. Complexes 1a and 1b are isostructural and show the formation of dinuclear meso-helicates with the two octahedral metal centers displaying respectively Δ and Λ configurations. These meso-helicates display large nanocavities with metal---metal separation distance of >2 nm; furthermore, π-π-stacking occurs among individual units to form one-dimensional (1D) polymers which further autoassemble in another direction through π-π contacts among neighboring chains to generate a two-dimensional (2D) network with regular nanocavities. Our approach might be of interest to prepare metal-organic nanotubes via a bottom-up strategy depending on the assembling functional ligand and the geometry of molecular building block.

In this study, we relate the contents of the journal Structural Chemistry for the calendar year 2007 and thermochemistry. The year's articles were briefly summarized and a thermochemical comment written to supplement them. Frequently questions were asked and future research was suggested.Keywords Structural Chemistry Á Thermochemistry Á Thermodynamics Á Enthalpy of formation Á Enthalpy of phase change Á Enthalpy of reaction As practiced disciplines, structural chemistry and thermochemistry are very often unrelated. In this study, these disciplines are linked as relations are explicitly made using the contents of the journal Structural Chemistry (Vol. 18) for the calendar year 2007 as a scaffold for our analysis, for our selected articles in the discipline of structural chemistry. These studies have been reviewed by us, where we give them a thermochemical flavor. While this commentary is most generally written in terms of brief summaries of literature papers involving enthalpies of formation and/or reaction, not uncommonly we raise questions and even suggest possible future research. We are not, however, going to give a thermochemical slant on book reviews, honorary dedications, and obituaries although these works will be cited in our text.As such, this article is a sequel to our earlier related reviews of Structural Chemistry for the calendar years 2000 through 2004 [1-5]. Reviews for 2005 and 2006 are currently being prepared. Issue 1In the first article in the first issue of Structural Chemistry for 2007, Hargittai [6] asserted that while research is currently usually carried out in big groups, the most important ideas, observations and discoveries still belong to individuals who have to bring down dogmas or open entirely new areas in science. This may bring solace to the thermochemical community in which research groups are generally small, and the number of new practitioners sadly few.In the past decade, the crystal engineering of multidimensional arrays and networks containing metal ions has achieved considerable progress because of the increased interest in the potential utility of these compounds as zeolite-like materials [7-11], catalysts [12], or magnetic materials [13][14][15]. The thermochemistry of these species is complicated by their inherent complexity: however, estimation approaches of their key thermochemical quantities are increasingly reliable [16]. In the second article of this issue, by Wang et al. [17], the versatility of malonate dianion as a ligand for the construction of extended networks with different topologies dependent on the coordination geometry of the metal ion was discussed. The synthesis and structure of a novel malonate-bridged copper(II) compound in which copper(II) ions have two different coordination environments in a novel three-dimensional (3D) network was described. Metal malonates have been studied from a
