From the reaction of CuICN with conc-NH4OH, a host-guest type 3D network complex , [[CuII(NH3)4(H2O)](H2O)@[CuI3(CN)5]]n was isolated and characterised. A unique cationic complex guest [CuII(NH3)4(H2O)]2+ is encapsulated in the anionic host cage [CuI3(CN)5]2-.

Luminescent pentanuclear tetra-decker Ln(III) complexes [Eu5L4(OH)2(NO3)4(H2O)2].NO3.3H2O , [Nd5L4(OH)2(NO3)5MeOH].3MeOH.2H2O and [Eu5L4(CF3SO3)4(MeO)2(H2O)4].CF3SO3.H2O are formed from Ln(NO3)3.6H2O (Ln = Eu (1), Nd (2)) and Eu(CF3SO3)3, respectively (H2L = N,N'-bis(5-bromo-3-methoxysalicylidene)phenylene-1,2-diamine).

The C1 Criegee intermediate, CH2OO, reaction with water vapour has been studied. The removal rate constant shows a quadratic dependence on [H2O], implying reaction with the water dimer, (H2O)2. The rate constant, kCH2OO+(H2O)2 = (4.0 ± 1.2) × 10(-12) cm(3) molecule(-1) s(-1), is such that this is the major atmospheric sink for CH2OO.

Knowledge of the physical state and morphology of internally mixed organic/inorganic aerosol particles is still largely uncertain. To obtain more detailed information on liquid-liquid phase separation (LLPS) and morphology of the particles, we investigated complex mixtures of atmospherically relevant dicarboxylic acids containing 5, 6, and 7 carbon atoms (C5, C6 and C7) having oxygen-to-carbon ...

Chloride-rich brines are increasingly recognized as playing an important role in high pressure and temperature metamorphic and magmatic systems. The origins of these saline multicomponent fluids are debated, but experimental evidence suggests that regardless of their origin they must be important agents of rock alteration and mass transfer wherever they occur. Studies of the solubility of quart...

Gas phase reactions between hydrated protons H+(H2O)n and a substance M, as seen in atmospheric pressure chemical ionization (APCI) with mass spectrometry (MS) ion mobility (IMS), were modeled computationally using initial amounts of [M] [H+(H2O)n], rate constants k1 to form protonated monomer (MH+(H2O)x) k2 proton bound dimer (M2H+(H2O)z), diffusion constants. At 1 × 1010 cm–3 (0.4 ppb) for [H...

A novel transition metal polyoxotungstate, [Cu(H2O)6][{Cu(H2O)2}2{Cu(H2O)4H4W12O42}] · 12H2O (1), has been synthesized in aqueous solution and characterized by single-crystal X-ray diffraction, elemental analysis, IR and UV/vis spectroscopy, and TG analysis. The paradodecatungstate anions [H2W12O42]10− are linked by CuO6 octahedra, forming a three-dimensional (3D) structure. The magnetic suscep...

x-ray photoelectron and electron energy loss spectroscopic (xps-eels) studies reveal that the following species are present when a mixture of co2 and water vapour is exposed to the clean mg(100) surface at 110k: co3(a), c(a) ch(a), oh(a). the reactive chemisorptions of co2 and h2o vapour coadsorbed on a mg surface leads to the formation of ch bond. increasing the temperature to 400 k shows the ...
