Seven new coordination polymers [Zn(I)2(4-bpmhz)]n (1), [Cd(I)2(4-bpmhz)]n (2), [Zn(I)2(3-bpmhz)]n (3), [Cd(I)2(3-bpmhz)2]n (4), [Zn(NO3)2(H2O)2(4-bpmhz)]n·0.5n(EtOH) (5), [Cd(NO3)2(4-bpmhz)3/2(MeOH)]n·0.5nH2O (6) and [Zn(NO3)2(3-bpmhz)2]n (7) were prepared following the reactions of the zinc and cadmium iodide or nitrate salts with the methylated azine ligands of the bis-monodentate N,N’-donor type, 1,2-bis(1-(pyridin-4-yl)ethylidene)hydrazine (4-bpmhz) and 1,2-bis(1-(pyridin-3-yl)ethylidene)hydrazine (3-bpmhz). The single-crystal X-ray diffraction studies show that compounds 1-5, and 7 display 1D chain structures, while compound 6 shows a 2D coordination network, and both 4-bpmhz and 3-bpmhz act as bidentate bridging ligands. The crystals 1 and 2 are isomorphous, and differ by the metal cation only. The single coordination chains in 1-3 have zigzag structures; they are linear in 5, while 4 and 7 display similar double-chain structures. The crystal packing in 5 and 6 provides cavities occupied by solvent mols., ethanol and water. The compounds were characterized in the solid state and in solution by spectroscopic (FTIR, UV-Vis, NMR) methods; the solid state emissive properties were studied for all compounds, while their thermal stability and behavior were investigated by thermogravimetry under inert atm., while the thermochromism for several compounds was registered and discussed.

Wholly heterocycles-based polyamide-sulfide (PAS) containing pyridine and thiazole rings with thioether linkage was synthesized and used as a novel adsorbent for lead ion removal from water. The polymer adsorbent was fully characterized via FTIR, NMR and SEM (SEM). The thermal properties of the synthesized polyamide were also studied by thermogravimetric anal. and the outcome showed that the polymer has a good to moderate thermal stability. The SEM was used to investigate the morphol. of the wholly heterocycles-based polyamide and the outcomes displayed a porous and globular-like morphol., which guarantee effective metal adsorption. Pb(II) ion removal capacity of the synthesized polymer was studied by varying the contact time and the adsorbent concentration The maximum removal of Pb(II) was obtained as 99%. Equilibrium behavior and kinetic of the adsorption were also investigated using prevalent isotherm and kinetic models. The adsorption capacity was obtained to be around 714 mg g-1. The Langmuir isotherm and the pseudo-second order kinetic model suggested superior agreement with the equilibrium and kinetic adsorption data, resp. Generally, the results of this research demonstrated that the synthesized polymer is a super-adsorbent for heavy metal removal from water.

The in air catalytic hydroboration of ketones and aldehydes with pinacolborane by an iron(II) coordination polymer (CP) is carried out under mild and solvent-free conditions. The precatalyst is highly active towards a wide range of substrates including functionalized ketones and aldehydes in the presence of KOtBu as an activator, achieving a high turnover number (TON) of up to 9500. Excellent chemoselectivity to aldehydes over ketones was also revealed, which is in sharp contrast with the results obtained under inert atm. using the same catalyst system. This catalyst observed here is not only highly efficient but also recyclable for reuse for at least 5 times without losing its effectiveness.

Herein authors report simple, efficient, and economically affordable metal-ligand cooperative strategies for synthesizing quinolines and quinazolin-4(3H)-ones via dehydrogenative functionalization of alcs. Various polysubstituted quinolines and quinazolin-4(3H)-ones were prepared in good yields via dehydrogenative coupling of readily available alcs. with ketones and 2-aminobenzamides, resp. under air using a well-defined Fe(II)-catalyst, ([FeL1Cl2]) bearing a redox-active azo-aromatic pincer 2-((4-chlorophenyl), (diazenyl)-1,10-phenanthroline) (L1). Control experiments and mechanistic investigation disclose that the one-electron reduced mono-anionic species [1]- bearing an iron-stabilized azo-anion radical ligand catalyzes these reactions. Both iron and the redox-active arylazo ligand participate synergistically during the different steps of these catalytic reactions.

Li, Bin; Yan, Qing-Qing; Yong, Guo-Ping published the artcile< Crystal structures and properties of four coordination polymers based on a new asymmetric ligand: Tuning structure/dimensionality by various organic solvents>, COA of Formula: C7H7NO, the main research area is cobalt nickel zinc cadmium bipyridinediyldibenzoato complex preparation crystal structure; photoluminescence magnesium cobalt nickel zinc cadmium bipyridinediyldibenzoato complex.

An asym. ligand, 4,4′-([2,3′-bipyridine]-4,6-diyl)dibenzoic acid (H2L) was successfully used to construct four new coordination polymers, [M(HL)2]n (M = Cd (1), Co (2), Zn (3)) and [Ni(L)(H2O)2]n·H2O (4), which were solvothermally synthesized and structurally characterized. In coordination polymers 1-4, two ligands bridge two metal centers through carboxylate oxygen atoms and pyridyl nitrogen atoms to form a rhombic grid motif. Amongst, each rhombic grid connects to adjacent ones through the metal nodes to construct spirolike 1-dimensional chain of 1-3 with the partially deprotonated 2-connected HL- ligands, whereas, the completely deprotonated 3- connected L2- ligands make rhombic grids construct 2-dimensional network of 4. The various structure/dimensionality of 1-4 essentially originates from the types of organic solvents, because dipolar DMF solvent results in complete deprotonated L2- in 4, conversely, polar NMP and MeCN only cause partial deprotonation of ligand in 1-3. An enhanced luminescence appears in 1 and 3, compared to H2L ligand, while 2 and 4 reveal antiferromagnetic behaviors. Also, the sensing experiments indicate that 1 and 3 possess luminescent quenching effects on sensing nitrobenzene. This work provides a promising approach to design and construct new coordination polymers with tunable structure/dimensionality by using different organic solvents.
