Cluster valenzelektronenarmer Metalle – Strukturen, Bindung, Eigenschaften

Abstract: Metalle in niederen Oxidationsstufen haben die Fahigkeit, Metall-Metall-Bindungen einzugehen. Es wird versucht, die Verbindungs-und Strukturenvielfalt bei metallreichen Systemen valenzelektronenarmer Metalle unter einem einheitlichen Blickwinkel zu ordnen. Hierzu werden von diesen Elementen gebildete Metallcluster, ihre Verknupfung und ihre Kondensation iiber gemeinsame Metallatome beschrieben, die schliel3lich zu ausgedehnten M-M-gebundenen Hereichen fiihrt. lnterstitielle Atome spielen eine wichtige Kolle be… Show more

“…5 c), generating the major part of V±V bonding in GeV 4 S 8 . According to metal cluster bonding theory [28,29], six equivalent 2-electron 2-center bonds along the edges of the V 4 tetrahedron were supposed for GeV 4 S 8 . But in fact the V±V bonds are made by three energetically different bonding states within the V 4 -cluster.…”

“…Cluster excision and subsequent ligand exchange reactions gives rise to a plethora of new compounds. [2][3][4][5][6][7][8][9][10][11][12][13][14] Recent investigations on early transition metal cluster compounds focus on using them as catalysts, [15,16] luminescent materials, [17,18] sensors, [19] medical X-ray contrast agents, [20,21] or as precursors for elaboration of nano-cluster materials. [22] For all such investigations on possible applications the knowledge about the synthesis, properties, and structures of as many as possible different compounds is essential.…”
