“…9). A wide range of well-defined M−OH complexes are known 82,112 and can be accessed through controlled hydrolysis routes. 44,110,[113][114][115] Subsequent deprotonation of the Brønsted acidic -OH proton with a highly Brønsted basic organometallic or metalamide reagent can generate a range of heterometallic oxo species.…”

The hydrolysis reaction between Brønsted basic organometallic or metal-amide reagents with Brønsted acidic OH groups from water or metal-hydroxides may act as a controlled stoichiometric strategy for the formation of M-O-M bonds, if careful consideration of reaction conditions is employed. This article explores the utilisation of highly reactive organometallic and metal-amide complexes from across the periodic table as reagents for the synthesis of metal-oxo clusters, oxo-bridged heterobimetallics and metal oxide nanoparticles. Such reactivity typically occurs at low temperatures with the release of hydrocarbon or amine by-products. The impact of ligand coordination, M-C bond strength, M-OH acidity and reaction temperature are discussed.

“…The scarcity of terminal hydroxo indium complexes is due in part to the tendency of hydroxide ions to bridge between metal centers [13–17], and there are many examples of systems containing bridging In(III)–(μ-OH)–In(III) units [17–21]. Far fewer examples of heterometallic systems involving In(III)–OH are known, with only 9 crystallographically characterized species [22–26]. …”

The use of the tripodal ligands tris[(N'-tert-butylureaylato)-N-ethyl]aminato ([H3buea]3−) and the sulfonamide-based N,N',N"-[2,2',2"-nitrilotris(ethane-2,1-diyl)]tris(2,4,6-trimethylbenzene-sulfonamidato) ([MST]3−) has led to the synthesis of two structurally distinct In(III)–OH complexes. The first example of a five-coordinate indium(III) complex with a terminal hydroxide ligand, K[InIIIH3buea(OH)], was prepared by addition of In(OAc)3 and water to a deprotonated solution of H6buea. X-ray diffraction analysis, as well as FTIR and 1H NMR spectroscopic methods, provided evidence for the formation of a monomeric In(III)–OH complex. The complex contains an intramolecular hydrogen bonding (H-bonding) network involving the In(III)–OH unit and [H3buea]3− ligand, which aided in isolation of the complex. Isotope labeling studies verified the source of the hydroxo ligand as water. Treatment of the [InIIIMST] complex with a mixture of 15-crown-5 ether and NaOH led to isolation of the complex [15-crown-5⊃NaI-(μ-OH)-InIIIMST], whose solid-state structure was confirmed using X-ray diffraction methods. Nuclear magnetic resonance studies on this complex suggest it retains its heterobimetallic structure in solution.
