Half-sandwich organometallic Ru and Rh complexes of (N,N) donor compounds: effect of ligand methylation on solution speciation and anticancer activity

A series of half-sandwich polypyridyl complexes was synthesized and compared focusing on structural, cytotoxic and aqueous solution behaviour. The formula of the synthesized complexes is [M(arene)(N,N)Cl]Cl, where M: Ru or...

Effects of organic ammonium cations on the isolation of {Ti4} cyclic clusters from water: an 17O NMR study

The organic ammonium cations change the solution speciation of Ti4+ in acidic water and promote the formation of {Ti18O27}. However, the crystalline precipitates are {Ti4} cluster compounds.

Crystallization behavior of citric acid based on solution speciation and growth kinetics

The work reports the crystallization study of citric acid in aqueous solutions, using a large variety of methods. The results are compared to Ostwald's rule of stages, leading to some contradictory results between the experiments and the rule.

Hierarchical phenomena in multicomponent liquids: simulation methods, analysis, chemistry

Complex, multicomponent, liquids benefit from a hierarchical understanding of solution speciation, collective organization and dynamics.

Polyoxometalates in solution: speciation under spotlight

The review covers stability and transformations of classical polyoxometalates in aqueous solutions and provides their ion-distribution diagrams over a wide pH range.

Modeling study of the heat of absorption and solid precipitation for CO2 capture by chilled ammonia

Prediction of (a) solution speciation change and (b) heat of CO2 absorption in the chilled ammonia process (CAP).

Complex formation of copper(ii), nickel(ii) and zinc(ii) with ethylophosphonoacetohydroxamic acid: solution speciation, synthesis and structural characterization

We present herein the thermodynamic and X-ray characterisation of a novel ethyl phosphonohydroxamic acid-based Cu(ii) metallacrown, predominating in solution in a broad pH range.
