The new heteroleptic complexes, [M(NCS)2(pia)2] M = Co(II) (1), Ni(II) (2), and [Cu(SCN)2(pia)2] (3), pia pyridine-2-carboxamide, were synthesized characterized. Their single crystal X-ray diffraction structures showed octahedral units, with the two thiocyanate ligands occupying cis-positions binding through nitrogen atom in Ni(II). In Cu(II) complex, they trans S-bound. display a 2-d structure NH⋯S hydrogen bonds for Ni(II), forming tetrameric are isomorphous Zn(II) [Zn(NCS)2(pia)2], NH⋯N...
A bifunctional ionic liquid (IL), bis-[N-(propyl-1-sulfoacid)-pyridinium] hexafluorotitanate (1), was synthesized and proved to be an efficient recyclable catalyst for room temperature sulfoxidation of sulfides using H2O2 as the oxidant. The synergetic catalysis derived from incorporated functional moieties in IL structure embodied 1. UV–vis Raman spectra indicated that remarkable catalytic performance 1 related easy generation regeneration active peroxo-Ti species.
Metal complexes of iminodiacetamide (imda) ligands and metal ions Zn(II), Cu(II), Ni(II), Co(II) were prepared using eight imda (L1–L8) substituted with groups different steric electronic properties on the central amine N atom (H atom, methyl, isopropyl, benzyl) para position phenyl rings (nitro dimethylamino). The effect these substituents stoichiometry (ML ML2), geometry, stereochemistry (mer, trans-fac, cis-fac) was studied in solid state, solution, by density functional theory...
Three picolinamide complexes of nickel(II) (1), zinc(II) (2), and cadmium(II) (3) have been prepared their solid state structures were determined by single-crystal X-ray diffraction analysis. Their in DMSO solutions as well the structure similar mercury(II) complex, [Hg(NO3)(pia)2](NO3) (4), elucidated 1H 13C NMR spectra. The is bound through N,O-donors all four state, but only 4 it solution state. In nickel zinc cadmium pia-N coordination suggested. analysis revealed that isomorphous (1)...
The reaction between 6-methylpicolinic acid (6-MepicH) and nickel(II) nitrate hexahydrate afforded a new octahedral complex containing two bidentate ligands water molecules in cis positions, which crystallized pseudopolymorphs, [Ni(6-Mepic)2(H2O)2]·2H2O (1) with cocrystallized from solution [Ni(6-Mepic)2(H2O)2] (2) without water.

Abstract The functionalized ionic liquids (ILs) of N ‐ n ‐dodecyl pyridinium vanadate ( 1 ), ‐(propyl‐1‐sulfonic acid) tetrafluoroborate 2 and 4‐(propanoate‐2,2,6,6,‐tetramethylpiperidine‐1‐oxyl) 5 ) were synthesized. mixture , in [Bpy]BF 4 yielded the compatible IL compositions (ILCs) as a homogenous mixture, which proved to be an efficient catalytic system for oxidation wide range alcohols using H O . With aid could easily recovered reused at least six runs without loss activity. UV/Vis...
Abstract A novel ionic complex, bis[1‐butyl‐2‐(diphenylphosphanyl)‐3‐methylimidazolium]tetrachloridoruthenium(III) hexafluorophosphate ( 2 ), has been synthesized and fully characterized. The single‐crystal X‐ray diffraction analysis showed that is composed of an Ru complex cation PF 6 – anion. a highly symmetrical Ru‐centered octahedron geometry with four Cl atoms in the equatorial plane two imidazolium‐substituted phosphane ligands axial positions. It exhibits paramagnetism due to presence...
A series of complexes HgX2(bzimtH2) and HgX2(bzimtH2)2 (X = Cl−, Br−, I−, SCN−; bzimtH2 benzo-1,3-imidazole-2-thione) was obtained by reaction the mercury(II) salts with benzo-1,3-imidazole-2-thione in appropriate molar ratio (1:1 or 1:2).
