Salt-like cluster ions of the ([cation](n)[anion](n-1))(+) type are commonly composed of mono-atomic, inorganic components. Clusters containing organic ions are also known, with nitrogen-centred cations being particularly prominent. However, sulphur-centred analogues, such as organic sulphonium salts, represent a notable exception. Fast atom bombardment and liquid secondary ion mass spectrometr...

The crystal structure of the pristine (I) and aged (II) crystals of CH3NH3PbI3 (hereafter MAPbI3) hybrid organic-inorganic lead iodide has been studied at 293 K with high-precision single-crystal X-ray diffraction using a synchrotron light source. We show that (I) and (II) are characterized by an identical tetragonal unit cell but different space groups: I422 for (I) and P42212 for (II). Both s...

Soil cation-exchange capacity (CEC) is often determined by NH4 saturation, using a 1M solution of NH4C2H3O2 at pH 7. A study was conducted to ascertain whether this determination can be performed by employing a simple diffusion technique previously developed for direct inorganic-N analysis of soils. Values obtained for 10 diverse Illinois surface soils following overnight NH4 saturation were co...

A new inorganic-organic hybrid compound [FTMA](2)[Co(NCS)(4)] (FTMA = ferrocenylmethyltrimethylammonium cation) has been synthesized and characterized by IR, UV, elemental analysis and X-ray crystallography. Co(II) atom has a distorted tetrahedral environment with four N atoms of four NCS(-) anions. In the solid state there are C-H⋯π interactions between adjacent ferrocenyl cations, which gener...

The title compound, (C(2)H(10)N(2))[In(HPO(4))(2)(OH)]·H(2)O, was synthesized under hydro-thermal conditions. The structure of this hybrid compound consists of isolated inorganic chains with composition (∞)[In(HPO(4))(4/2)(OH)(2/2)] running along [010]. The coordination of the In(III) atom is distorted octa-hedral. The ethyl-enediammonium cation and the disordered water mol-ecule (site-occupati...

In this paper, we report the preparation of nickel phosphate in aqueous solution and its use as inorganic pigment. Because cerium phosphate is insoluble in acidic and basic solution, the addition of cerium was tried to improve the acid and base resistance of nickel phosphate pigment. The cerium substituted nickel phosphates were prepared from phosphoric acid, nickel nitrate, and ammonium cerium...

The title compound, {(C(14)H(18)N(2))[Pb(2)I(6)]}(n), consists of discrete 1,1'-dimethyl-4,4'-(ethane-1,2-di-yl)dipyridinium cations and one-dimensional [Pb(2)I(6)](n) anions. The organic cation has an inversion center at the mid-point of the ethane C-C bond. In the anion, the Pb(II) atom is coordinated by six I atoms in a distorted octa-hedral geometry. The I atoms bridge the Pb(II) atoms into...

Commercial purity Mg and Mg-alloy AZ61 were exposed at open circuit potential under anodic polarization in two ionic liquids containing 10 wt% of water, formed by acetate anion methylpyrrolidinium cation, substituted with either aliphatic (ILA) or etheric (ILE) chain. Hydrogen evolution strongly increased (negative difference effect, NDE) ILA, but not ILE. In both electrolytes Mg(OH)2-film on A...

p-Nitroaniline presents the typical motif of a second-order nonlinear optically (NLO) active molecule. However, because of its crystallization in an antiparallel and hence centrosymmetric structure, the NLO activity is lost. In this contribution, the p-nitroaniline motif was built successfully into the MIL-53 metal-organic framework. More precisely, MIL-53 was synthesized with 2-amino-5-nitrote...

Abstract The astonishingly distinct lubricity difference between the ionic liquid modified carbon nanoparticles grafted by anion and cation moieties (A-g-CNPs C-g-CNPs) was well established as additives of polyethylene glycol (PEG200). peripheral positively charged inner parts C-g-CNPs could successively absorb onto friction interfaces electrostatic interactions to form organic—inorganic electr...
