“…58 For synthetic reasons and owing to better kinetic stabilization, most of the other reported heavier group 13 and 14 congeners exhibit shielding by silyl substituents, such as found in ( t Bu3SiTr)4 (Tr = Al, Ga), ( t Bu3SiTt)4 (Tt = Si, Ge) and (LTr)4 (L = (Me3Si)3C; Tr = In, Tl). [13][14][15][16][17][18][19][20][21]59 However, there are a few special cases: anionic [{(SiMe [{(SiMe3)3C}6Ga8] was obtained under similar conditions, by reaction of GaBr with LiC(SiMe 3 ) 3 at −78°C. However, the molecular structure of the latter shows obvious differences compared to the {Al 7 } motifs, with two tetrahedral {Ga 4 } units being linked through a Ga−Ga bond.…”

Compounds containing (pseudo-)tetrahedral main group (semi-)metal units are fundamentally important in three regards. Firstly, they provide us with new strategies for the stabilization of tetrahedral units, such as Pn 4 (Pn = P, As) and their isoelectronic analogs, in the coordination sphere of d-/f-block metal atoms. Secondly, they serve as first-step models for the activation of tetrahedral molecules. Thirdly, they are starting materials for subsequent transformations towards larger clusters or materials. Partial or full isoelectronic replacement of the pnictogen atoms in P 4 or As 4 results in a variety of (pseudo-)tetrahedral anions, Tt 4 4− (Tt = Si, Ge, Sn, Si/Ge), (Ge3Pn) 3− (Pn = P, As; formed in situ), (Tt2Pn2) 2− (Tt/Pn = Ge/P, Ge/As, Sn/Sb, Sn/Bi, Pb/Sb, Pb/Bi), or (TrBi3) 2− (Tr = Ga, In, Tl), and also cations, (P3Ch) + (Ch = S, Se, Te). The anions proved to be excellent starting materials and building blocks for multinary clusters in the context of Zintl chemistry. Such compounds, which push forward the boundary of the intriguing P 4 chemistry, have never been thoroughly summarized before. In this mini review, we introduce all known intact (pseudo-)tetrahedral group 13−15 units, as well as the coordination compounds based on them, along with two new missing links, [Au(η 2 -Tt2Bi2)2] 3− (Tt = Sn, Pb).

An update for select advances in the chemistry of organoindium compounds containing at least one In–C bond is reported. In particular, the various synthesis protocols to these are discussed, as well as characterization of homoleptic and heteroleptic organoindium derivatives; organoindium (0), (I), and ( II ) compounds; and anionic compounds is also reported. An examination of mixed metal complexes is also reported for both low valent systems as well as for In( III ) oxidation state. Furthermore, the use of organoindium compounds for thin film, nanotechnology organic synthesis, and catalysis is discussed.
