In the crystal structure of the title compound, [CuCl(C(5)H(5)N)(4)][N(CN)(2)]·2C(6)H(5)N, the copper(II) cations are coordinated by one chloride anion and four N-bonded pyridine ligands into discrete complexes. The copper(II) cation shows a square-pyramidal coordination environment, with the chloride anion in the apical position. However, there is one additional chloride anion at 3.0065 (9) Å,...

The use of commercially available cation and anion exchange membranes to generate power from industrial wastewater obtained from three different industries (food, alcohol and dairy factories) without the addition of external microorganisms or chemicals by using microbial fuel cells (MFCs) was investigated. The results indicate that the original mixed culture of microorganisms presented in waste...

Trans-diaqua[meso-tetrakis(4-pyridyl)porphyrinato]Sn(IV) dinitrate complexes were assembled in a two-dimensional manner via hydrogen bonding between aqua ligands and pyridyl substituents. Interestingly, this supramolecular assembly was accompanied by unconventional noncovalent interactions, such as anion···anion anion···? which confirmed X-ray crystallographic analysis. Two nitrate anions close...

The alkali halides interaction with d-ribose in D2O solutions was studied by 1H and 13C NMR spectroscopy. The observed changes in the NMR spectra are interpreted according to a model in which the hydroxyls rich region, from C1 to C4, interacts with the cation while the CH2 group at C5 on the opposite side of the sugar interacts with the anion. It seems, during the salt-sugar interaction, cation...

The asymmetric unit of the title compound, C(17)H(24)NO(+)·Cl(-), consists of a discrete N-(2-hy-droxy-benz-yl)adamantan-1-aminium cation and a Cl(-) anion. Inter-molecular N-H⋯Cl and O-H⋯Cl hydrogen bonds occurring between the organic cation and the Cl(-) anion generate a layered structure.

The title compound, (C(21)H(25)N(2))[ReO(4)], was formed as the unexpected product in an attempted synthesis of a rhenium(I)-N-heterocyclic carbene (NHC) complex. The compound has crystallographic mirror symmetry with both the cation and the tetrahedral anion located across a mirror plane. The cation and anion are linked by a C-H⋯O hydrogen bond.

The grain boundaries (GBs) in the absorber of a Cu(In,Ga)(S,Se)2 (CIGS) solar cell play vital role its efficiency and cells with polycrystalline absorbers exhibit high conversion (>23%). Previous investigations confirm that traits GBs CIGS are directly connected to their composition. However, such relationship cannot be established for twin (TBs). This is because although electron beam-induced ...

No fluorescence emission of the naphtholate anion is observed from ionic liquids with an imidazolium cation containing a C2 hydrogen (C2-H). This is attributed to the formation of a "dark" complex between the imidazolium cation and the excited naphtholate anion.

The title compound, [Au2(C27H26P2)2][NiCl4]·C4H10O, consists of a digold(I) complex cation, an [NiCl4](2-) complex anion and a diethyl ether solvent mol-ecule. Two 1,3-bis-(di-phenyl-phosphan-yl)propane (dppp) ligands bridge two Au(I) atoms, forming a metallacycle in which each of the Au(I) atoms is coordinated in a slightly distorted linear environment by two P atoms. In the complex anion, the...

Combined data of photoelectron spectra and photoionization efficiency curves in the near threshold ionization region of isolated ion pairs from [emim][Tf(2)N], [emim][Pf(2)N], and [dmpim][Tf(2)N] ionic liquid vapors reveal small shifts in the ionization energies of ion-pair systems due to cation and anion substitutions. Shifts toward higher binding energy following anion substitution are attrib...
