“…Regarding monomeric [ZnCp*] radicals, pure [Zn n Cp* m ] ( n > m ) cluster compounds had also been unknown until recently, due to their tendency to spontaneously dimerize . In 2016, the formation of metalloid clusters of the type [Zn n Cp* m ] was achieved with [Zn 10 Cp* 6 Me] + , [Zn 9 Cp* 6 ], and [Zn 8 Cp* 5 ( t BuNC) 3 ] …”

This review article provides a survey of contemporary investigations on main group metal cluster formation, addressing homo- and heterometallic clusters (including small numbers of transition metal atoms), with or without an external ligand shell, thereby excluding clusters with non-metal atoms as bridging ligands. Most of the studies reflected herein represent insights into the formation of intermediates from the starting material, or the final cluster formation from established intermediates. In rare cases, the entire process was suggested as a result of comprehensive, multi-method elucidations. The article is to be understood as a state-of-the-art report, as the subject matter is currently a rising field of research, which is still in its infancy, despite some early activities that date back to the 1980s. At the same time, the article intends to point toward both the importance and the feasibility of according studies, in order to encourage researchers to gain even more knowledge in this field. Only deep understanding of cluster formation will allow for design, and ultimately control, of their syntheses, with the long-term goal of their optimization and purposeful application in catalysis or novel material synthesis.

Atompräzise und ligandenstabilisierte metalloide Cluster haben sich als herausragende Modellsysteme für grundlegende Struktur‐ und Bindungssituationen in kompositionell verwandten Molekülen und Festkörperphasen erwiesen. Dieses faszinierende Forschungsfeld ist jedoch noch immer stark auf Systeme homometallischer und pseudo‐homometallischer verwandter d‐Block‐Metalle beschränkt. In diesem Aufsatz möchten wir unsere eigenen sowie die Leistungen anderer hervorheben, um die strukturelle und kompositionelle Vielfalt intermetallischer Phasen mit ungleichen d‐ und p‐Block‐Metallkombinationen auf molekularem Level darzustellen, im Besonderen anhand der Zintl‐ und Hume‐Rothery‐Phasen. Ziel ist es, die Kluft zwischen der heterometallischen molekularen Koordinationschemie und den Festkörperphasen zu überbrücken. Hierbei werden grundlegende synthetische Herangehensweisen sowie strukturelle und elektronische Eigenschaften solcher “molekularer Legierungen” angesprochen und ihre außergewöhnliche Position als Zwischenschritt auf dem Weg zu Nanomaterialien hervorgehoben.

Intermetalloid Clusters: Molecules and Solids in a Dialogue

Atom-precise, ligand-stabilized metalloid clusters have emerged as outstanding model systems to study fundamental structure and bonding situations of compositionally related molecules and extended solid phases. However, this fascinating field of research is still largely restricted to homometallic and pseudo-heterometallic systems of closely related d-block metals. In this review, we will highlight our own and others' efforts to project the structural and compositional diversity of intermetallics with dissimilar d- and p-block metal combinations, particularly the Zintl and Hume-Rothery phases, onto the molecular level in order to bridge the still gaping chasm between heterometallic molecular coordination chemistry and solid-state intermetallics. Herein, fundamental synthetic approaches, as well as structural and electronic properties of thus accessible "molecular alloys" will be addressed, and placed against their exceptional position as intermediates on the way to nanomaterials.
