The adsorption of homologous alkyldimethylbenzylammonium bromides, [C(6)H(5)CH(2)N(CH(3))(2)R]Br, on sodium montmorillonite from aqueous NaCl solutions at room temperature has been studied. R stands for the methyl-, butyl-, hexyl-, octyl-, decyl-, and dodecyl-group, and the corresponding ammonium cations will be denoted as C1+, C4+, C6+, C8+, C10+, and(More)
The molecular and crystal structures of N-benzyl-N,N-dimethylalkylammonium bromides monohydrates with chain length n=8-10 have been determined. The crystals are isostructural with the N-benzyl-N,N-dimethyldodecylammonium bromide monohydrate. The structures consist of alternated hydrophobic and hydrophilic layers perpendicular to [001]. The attraction(More)
The reactions of tetrazole ligand derived from 2-cyanopyridine with K3Na[Mo(CN)4O2]·6H2O and K3Na[W(CN)4O2]·6H2O in water-ethanol solution result in isolation of two new complexes with the following formulae: (PPh4)2[Mo(CN)3O(pdt)]·2H2O (1) (Hpdt = 5-(2-pyridil)-1H-tetrazole) and (PPh4)2[W(CN)3O(pdt)]·3H2O (2). The complexes were characterized by elemental(More)
Crystals of the title compound, C(16)H(28)N(+).Br(-), were grown from solution in a mixture of acetone and propan-2-ol by slow evaporation. The structure was solved in the polar space group P4(2)bc with five moieties in the asymmetric unit, namely two benzyltripropylammonium cations in general positions, and two Br(-) anions in special Wyckoff positions(More)
A new layered mixed-linker metal-organic framework [Zn2(iso)2(pcih)2]n (MOF) built from isophthalate ions (iso(2-)) and 4-pyridinecarbaldehyde isonicotinoyl hydrazone (pcih) was prepared using both solution and mechanochemical methods. By use of the latter, the 2D MOF is obtained either in a one-mortar three-component grinding or on the way of a two-step(More)
The reactions of a mother solution of RuCl(3) with benzimidazole derivatives 2-(2'-pyridyl)benzimidazole (2,2'-PyBIm, L(1)) and 2-hydroxymethylbenzimidazole (2-CH(2)OHBIm, L(2)) yielded three novel ruthenium complexes: (H(2)L(1))(2)[Ru(III)Cl(4)(CH(3)CN)(2)](2)[Ru(IV)Cl(4)(CH(3)CN)(2)]·2Cl·6H(2)O (1), mer-[Ru(III)Cl(3)L(1)(CH(3)CN)]·L(1)·3H(2)O (2), and(More)
A novel single site Mn(II) complex was successfully synthesized and tested in the aqueous disproportionation of hydrogen peroxide. The complex was found to be stable (HR-XAS) and exhibits catalase-like activity in neutral pH. Theoretical calculations suggested a reaction mechanism involving two complexes, changes in metal oxidation state and proton(More)
The crystal structure of the title compound, C(11)H(18)N(+)·Br(-), has been determined as part of an ongoing study of the influence of the alkyl chain length on amphiphilic activity of quaternary ammonium salts. The title salt forms a three-dimensional network of ionic contacts through weak C-H⋯Br hydrogen bonds, with donor-acceptor distances in the range(More)
Crystal, molecular and electronic structure of new manganese(II) compounds: [Mn(2-CH2OHpy)2(NO3)2] (1), [Mn(4-CHO-5-MeIm)2(NO3)2] (2) and [Mn(4-CHO-5-MeIm)2Cl2] (3), where 2-hydroxymethylpyridine (2-CH2OHpy) and 5(4)-carbaldehyde-4(5)-methylimidazole (5(4)-CHO-4(5)-MeIm), have been characterised using X-ray, spectroscopic, magnetic and TG/DTG data.
