Polyoxymethylene dimethyl ethers are a new type of diesel fuel additive, and are synthesized by using trioxymethylene and methanol as raw material and ionic liquid as catalyst. In the experiment, the effect of catalyst dosage, ratio of raw materials, reaction temperature, time and pressure, and reusing times of catalyst were studied. The results showed that when the reaction was carried out under the conditions of 5 wt% catalyst, m(Trioxymethylene)/m(Methanol) 1.5, temperature 110°C, time 4 h, pressure 2.0 MPa, conversion of trioxymethylene is 94.25%. The ionic liquids could be reused five times without noticeable drop in activity.

In this work the ternary metal complexes of Cu(II) and UO2(II) with some Schiff bases derived from 2-hydroxy-1-naphthaldehyde and some amino acids as a primary ligand and two different heterocyclic bases as a secondary ligand have been synthesized. FT-IR results disclosed that the Schiff bases are coordinated to the central metal ion as a bivalent tridentate ONO donor. Electronic absorption spectra showed bands that are very distinguishable to copper and UO2(II) ternary complexes. Furthermore, the effect of these complexes on the gram-positive bacteria is more than their effect on the gram-negative bacteria.

The complex has been characterized by elemental analysis, IR spectra, X-ray crystal diffraction, cyclic voltammetry, and thermogravimetry.

AbstractInteraction of metal NPs with different number of ILs was studied. Basically, different energies for the interaction of various metal NP with the different number of tetrazole based ionic liquid were calculated. Herein, energies in terms of moldoc and rerank score have been calculated. How metal NPs interacts with ionic liquid in different ratio? Ionic liquid interaction energy increases on increasing the number of ionic liquids both in case of moldoc score and rerank score. Only exception has been seen when two molecules of ionic liquids interact with metal NPs showed the maximum stability. As far as metal NPs-IL interaction energy is concerned it again follows the same trend, it increases but again decreases in case of two ionic liquids. Steric interaction energy is also following the same trend. This energy is pairwise energy. Further, the deciding factor for the stability is the total energy and it increases with increase in number of IL and therefore, when the interaction of metal NPs was car...

The authors focused on the preparation of thin layers based on hybrid materials (organometallic complexes) deposited onto glass substrates. The deposition experiments of [Ni(bpy)3](NCS)2, [Ni(bpy)3](Ag(CN)2)2, and [Ni(bpy)3](Fe(CN)5NO) were performed on glass slides (18 mm × 18 mm) by successive ionic layer adsorption and reaction (SILAR) method. The influence of some parameters, such as dipping cycle numbers (30, 60, and 120 dipping cycles), temperature (20°C, 30°C, 40°C, and 50°C), precursors concentration (10−3, 10−2, and 10−1 M), and the nature of the counteranions (NCS−, [Fe(CN)5NO]−2, [Ag(CN)2]−) were studied. Different methods (UV-Vis, SEM, FTIR, and XRD) were used to characterize the deposited layers to determine the absorption coefficient (α) and gap energy (Eg) of the materials.

A new cis-dioxomolybdenum(VI) complex, [MoO2LMeOH] (1) and a new oxovanadium(V) complex, [VOL(OMe)MeOH] (2), with potentially tridentate ONO aroylhydrazone Schiff base derived from 4-methoxysalicylaldehyde with 4-trifluoromethylbenzohydrazide, have been synthesized and fully characterized on the basis of elemental analysis, FT-IR, molar conductivity, and electronic spectra. Structures of the complexes have been accomplished by single-crystal X-ray diffraction. The complexes have distorted octahedral structures in which the aroylhydrazones behave as binegative ligands. It is also revealed from the crystal structures that the Mo(VI) and V(V) centers adopt NO5 donor environment, and the octahedral coordination is furnished by oxido groups and oxygen atoms of methanol or deprotonated methanol molecules. The catalytic properties were investigated for epoxidation of cyclooctene using aqueous tert-butyl hydroperoxide as the oxidant.

Reaction of copper perchlorate with the tridentate Schiff bases N,N’-bis(5-methoxysalicylidene)-1,2-ethanediamine (H2L1) and N,N’-bis(5-chlorosalicylidene)-1,3-propanediamine (H2L2), afforded a dinuclear complex, [Cu2(L1)2]·2CH3OH (1), and a mononuclear complex, [CuL2] (2). The complexes were characterized by single-crystal X-ray diffraction, FT-IR, and elemental analysis. The Cu atom in complex 1 is in a square pyramidal coordination, with two phenolate O and two imine N atoms of L1 ligand defining the basal plane, and with one phenolate O atom of another L1 ligand occupying the apical position. The Cu atom in complex 2 is coordinated by two phenolate O and two imine N atoms of L2 ligand, forming a tetrahedrally distorted square planar geometry. The free Schiff bases and the complexes were assayed for antibacterial activities. Both complexes are more active against the bacteria than the free Schiff bases. Complex 2 has the MIC value of 0.10 μg mL−1 against Bacillus subtilis.

Supramolecular coordination compounds have been widely surveyed as they represent an important interface between synthetic chemistry and materials sciences. Nanostructure of a new dinuclear 11-coordinated complex of lanthanum(III) with the ligand 1,4-bis(3-pyridyl)-2,3-diaza-1,3-butadiene(3-bpdb),[La(3-bpdb)1/2(H2O)4(NO3)3]2.H2O.3-bpdb (1), was synthesized by a sonochemical method, and these transformations have been verified by X-ray powder diffraction, FT-IR spectroscopy, and scanning electron microscopy. Crystal composition as determined by single-crystal X-ray analysis reveals that it belongs to the triclinic space group Pī. The crystal structure of this compound has been studied. Also, compound 1 has been used as a precursor of the synthesis of La2O3 nanostructure. The crystallininty and morphology of the La2O3 nanostructure were characterized by SEM, FT-IR and XRD.
