“…The situation is even more ambiguous if the 18-electron configuration is not obligatory for either metal (e.g. those in Groups 4,5,8,and 9). While it is debatable if the metal ± metal interactions in unsaturated dinuclear organometallic compounds (i.e.…”

Interactions between a pair of transition-metals can range from weak antiferromagnetic coupling to bonds of the highest multiplicity known in chemistry, for example, quadruple in isolatable compounds. Tremendous effort has been invested in studying homodinuclear transition-metal-metal bonds. In contrast, relatively little attention has been devoted to heterodinuclear analogues, as it is substantially more challenging to prepare and handle such entities. Yet, in this largely unexplored area of transition-metal chemistry, novel chemical interactions with unprecedented reactivities are likely to be found. Heterodinuclear analogues of diatomic transition-metal dimers being yet inaccessible, dinuclear complexes with Werner-type ligands provide examples of high-multiplicity bonds between different d elements in their least-perturbed form. Such compounds provide an opportunity to probe fundamental issues of chemical bonding between transition-metals, by revealing how and to what extent such bonds are affected by differences in the two metals. Complexes wherein electronically unsaturated heterodinuclear cores are stabilized by pi-acidic ligands (such as CO) hold the potential of new chemical reactions (including catalytic) that capitalize on the synergetic effect of two transition-metal centers.

“…The strategy to reductively exchange iron by gallium has proven valuable due to the low detection limits obtained for gallium compared to iron with LC−ICP-TOFMS. The use of gallium is today mainly restricted to two areas: the semiconductor industry and in medicine for organ scanning and as an anticancer agent . In these fields, as well as in studies of the increasing levels of gallium in the environment and what effect it has on different biological species, there may also be a growing need for sensitive analytical methods where gallium is separated from other elements or where gallium-containing species are separated from each other.…”

Fingerprinting Metal-Containing Biomolecules after Reductive Displacement of Iron by Gallium and Subsequent Column-Switched LC−ICPMS Analysis Applied on Siderophores

Column-switching liquid chromatography followed by low-resolution ICPMS was evaluated as a tool for speciation analysis of metal-containing biomolecules. The strategy was applied on siderophores, strong iron chelators of low molecular weight (M(w) < 1500). Prior to the LC-ICPMS analysis, reductive displacement of iron by gallium was performed using ascorbate as the reducing agent to increase the sensitivity. Different experimental conditions during the exchange reaction were tested using ferrichrysin and ferrichrome for evaluation. A reaction time of 30 min and a pH of 3.9 gave an exchange yield of 27 and 83% for ferrichrysin and ferrichrome, respectively. A gradient elution profile was also developed to separate gallium-chelated siderophores on a PGC column. Detection limits for standard solutions of ferrichrysin and ferrichrome in the low-nanomolar range were obtained by monitoring the gallium-69 isotope. The combined use of LC-ICPMS and LC-ESI-MS/MS was also evaluated as a tool to identify unknown metal complexes, here siderophores, in field soil solution samples.

An overview of the inorganic chemistry of gallium and its compounds is reported in detail with an attempt to bring up to date current studies in this field. In addition, the use of various Ga related alloys as either binary or ternary semiconducting material for bulk, thin film, and nanotechnology is reported in detail pertaining to their synthesis, properties, and application. The chemistry of Ga inorganic and coordination derivatives is also reviewed and discussed.
