“…Cooper and Macdonald demonstrated that is it possible to displace the indium(I) ion from [18]crown-6 with a potassium ion. 179 For example, the treatment of solutions of the very soluble [In( [18]crown-6)][OTf] complex with KX (X = Cl, Br, I), results in the immediate formation of finely dispersed powders of InX. Such finely dispersed indium(I) halides may have practical applications in synthetic applications given the insolubility and instability of the bulk indium(I) halide salts.…”

Notable aspects of the chemistry of complexes of polyether ligands including crown ethers, cryptands, glycols, glymes, and related polyether ligands with heavier group 13 and 14 elements are reviewed with a focus on results from 2005 to the present. The majority of reported polyether complexes contain lead(ii) and thallium(i) but recent breakthroughs in regard to the preparation of low oxidation state reagents of the lighter congeners have allowed for the generation of complexes containing indium(i), gallium(i), germanium(ii), and even silicon(ii). The important roles of ligand size, donor types, and counter anions in regard to the chemical properties of the polyether complexes is highlighted. A particular focus on the structural aspects of the numerous coordination complexes provides a rationale for some of the spectacular contributions that such compounds have made to Modern Main Group Chemistry.

“…77 Treatment of [In(18-crown-6)]-[O 3 SCF 3 ] with several potassium salts has resulted in the release of the indium(I) cation from the crown ether and the production of salts of [K(18-crown-6)] + and uncomplexed [In] + . 78 A fluoro-metallocrown has been found to bind caesium, extracting it from aqueous solutions into an organic layer. 79 A calix-4-arene-calix-4-pyrrole, a receptor with three different caesium recognition modes has been described.…”

Advances in the coordination and inorganic chemistry of the elements of Groups 1 and 2 of the periodic table from the calendar year 2010 are summarised in this non-critical review. As was the case in previous years, coverage concentrates on topics centred around the synthesis, structures and applications of coordination compounds and the organometallic chemistry of these elements. HighlightsThe isolation and reaction chemistry of kinetically-stabilised Group 2 species in which the alkaline earth centre exists in a formal +1 oxidation state has received intense international attention while interest in the potential of alkaline earth complexes as benign and inexpensive reagents for catalysis has continued to develop.

The use of the univalent indium reagent [In([18]crown-6)][OTf] as a donor is investigated by its reactions with acceptors including InX(3) (X=Cl, Br, I). The donor-acceptor complexes of the form [X([18]crown-6)In-InX(3)] obtained in this manner represent the first new isomeric form of indium(II) halides identified for at least five decades. The formation of such complexes appears to be particularly favorable and they are isolated as products in many reactions involving low-valent indium, a halide source, and [18]crown-6. A convenient solution-phase synthesis of In[ECl(4)] salts is reported. This facile and direct syntheses of In[ECl(4)] (E=Al, Ga, In) salts allows for the in situ preparation and isolation of crown-ether complexes of the form [In([18]crown-6)][ECl(4)], whose existence had been postulated but never confirmed. Solution-phase and solid-state NMR experiments reveal that these compounds can exist as either donor-acceptor complexes or ionic salts, depending on the phase of the system, the nature of the solvent employed, and the identity of the metalate anion involved. Similar investigations into the effect of a smaller crown ether allow for the isolations of salts containing the cation [In([15]crown-5)](+). Computational investigations into the nature of the crowned univalent indium donor fragments, and on the donor-acceptor complexes produced, demonstrate the influence of anionic substituents on the reactivity of lone pair of electrons of the In(I) center. Natural bond orbital (NBO) analysis of donor-acceptor models shows that the composition of the E-E bond MO should provide the ability to predict which models should form stable complexes.
