Nitrido‐Komplexe von Übergangsmetallen

Synthese und Struktur von dreikernigen Heterometall-Komplexen mit Nitridobrücken zwischen Re und Sn

“…Durch die Bru È ckenfunktion der Nitridoliganden werden die Re±N-Absta È nde (Re(1)±N(1) = 168,0(9) pm, Re(2)±N(2) = 168,3(9) pm) gegenu È ber der terminalen Bindung im Edukt ReNCl 2 (PMe 2 Ph) 3 (166,0(8) pm [6]) nicht merklich aufgeweitet. Sie entsprechen der Erwartung fu È r Dreifachbindungen [7,8], wa È hrend die Absta È nde Sn(1)±N(1) = 226(1) pm und Sn(1)±N(2) = 225(1) pm mit koordinativen Einfachbindungen interpretiert werden ko È nnen.…”

Synthese und Struktur von zwei- und dreikernigen Heterometallkomplexen mit Nitridobrücken zwischen Re und Mo

“…The reaction of ReNCl 2 (PMe 2 Ph) 3 with MoCl 4 (NCEt) 2 [5,6]. Besonders starke Lewis-basische Eigenschaften weist der von Chatt et al [7,8] dargestellte Rhenium(V)-Nitridokomplex ReNCl 2 (PMe 2 Ph) 3 auf.…”

Kurt Dehnicke (1931–2011)

“…[5] A further preparative coup was the synthesis of MNCl 3 (M = Mo, W) with a metal-nitrogen triple bond in 1965, [6] which formed the basis of the DFG program "Nitrido Bridges" that Kurt Dehnicke initiated and led (1995/96). [7][8][9] Kurt Dehnickes preference for particular elements could be seen in the development of inorganic complex chemistry (for example with Re, Os, Mo, W) of small, reactive, and multiatom species with bonding situations that are interesting from a theoretical viewpoint, such as nitrosyl, thionitrosyl, chloro-and bromothionitrenes, and dichloroselenonitrenes, [10] or phosphiniminato complexes of main-group elements, transition metals, [11,12] and rare-earth metals. [13] Further remarkable results were the preparation of triazyl chloride and tetraselenium tetranitride as well as comprehensive and groundbreaking work on new anionic chains, such as [Se n ] 2À (n = 5-6) and bicyclic polyselenides [Se n ]…”
