The spin-crossover (SCO) phenomenon between a high-spin and a low-spin state has attracted much attention in the field of materials science. Among the various kinds of SCO complexes, the triazole-bridged iron(II) polymeric chain system, [Fe(II)(R-trz)3]X2·xH2O (where trz is triazole and X is the anion), exhibiting the SCO phenomenon with thermal hysteresis around room temperature, has been exte...

In the title compound, C(13)H(15)N(2) (+)·PF(6) (-), the dihedral angle between the two aromatic rings is 85.48 (7)°. In the crystal, C-H⋯F hydrogen bonds connect the imidazolium and hexa-fluoro-phosphate ions.

Different Chiral Ionic Liquids (CIL) based on L-proline have been developed. Simple and efficient synthetic methodologies are used, allowing preparation in good yields for twelve novel CILs using as a cation or anion combined with suitable counter-ions. A detailed physical chemical characterization of the was performed to evaluate influence counter-ions final properties. The most promissory wer...

Decomposition and corresponding mechanism of alachlor, an endocrine disruptor in water by ozonation were investigated. Results showed that alachlor could not be completely mineralized by ozone alone. Many intermediates and final products were formed during the process, including aromatic compounds, aliphatic carboxylic acids, and inorganic ions. In evoluting these products, some of them with we...

In the crystal structure of the title salt, C7H12N2 (2+)·2NO3 (-), the nitrate ions are located in the vicinity of the protonated amine groups, accepting strong N-H⋯O hydrogen bonds. Each ammonium group is involved in a total of three such inter-actions with neighbouring nitrate ions, generating a three-dimensional network. In addition, there are π-π inter-actions between the aromatic rings of ...

In view of the fact that the phosphorus atom in its low co-ordination state (coordination numbers 1 and 2) has been termed as the carbon copy, there have been attempts to investigate, theoretically as well as experimentally, the effect of the exchange(s) of CH- moiety with phosphorus atom(s) (CH/P) on the structural and other aspects of the classical carbocyclic and heterocyclic systems. Tropyl...

We present a series of experimental results that disclose the crucial role of ionic strength and partial volume fractions in the control of the phase behaviour of binary protein mixtures. Our findings can be understood as that the ionic strength determines the relative contribution of the entropy of the protein counter-ions to the overall thermodynamics of the system. Associative phase separati...
