Azoalkan‐ und Nitren‐verbrückte Carbonylmetall‐Cluster des Eisens und Rutheniums

Abstract: Azoalkane-and Nitrene-Bridged Carbonyl Metal Clusters of Iron and RutheniumBy using cluster buildup reactions, the new azoalkane-bridged cluding the new compound Fe,(C0)11(b4-NEt)2 (9). Cluster clusters Ru3(CO),(RN=NR) (3a, R = Me, 3b, R = Et), buildup starting from Ru3(C0)9(p3-NPh)2 resulted in Fe2Ru(CO),(EtN =NEt) (4), RU~(CO)~~(RN=NR) (5a, R = Me, R U~( C O )~~(~~-N P~) , (10) and F~R u~( C O )~~(~~-N P~)~ (11). The 5b, R = Et), and FeRu3(CO)12(EtN=NEt) (6) were obtained. crystal structures of 5b and 9 as w… Show more

“…There are, as yet, no known examples of heteronuclear clusters relevant to this section which contain an E atom bridging a square metal face (Structure (83)), although the homonuclear ruthenium cluster [Ru 4 ((i 4 -Bi) 2 (CO) 12 ]418 demonstrates this bonding mode. The cluster [Mo 2 Co 3 (n 5 -N)(CO), 0 Cp* 2 ] 342 provides a rare example of a pentacoordinated semiinterstitial nitrogen, while the high nuclearity clusters [Rh 6 M(n 6 -N)(CO), 5 ] 2( M = Co or Ir)412 and [Rh 10 Pt(ji 5 -N)(CO) 21 ] 3~4I6 contain fully encapsulated nitrogen atoms in somewhat irregular environments.The imido ligand NR is found almost exclusively in the | x 3 bonding mode in the heteroclusters reported in this wor k,61 ' 112 ' 231 ' 342 ' 349 ' 368 ' 369 ' 376 ' 377 the one exception being [FeRu 3 (ji 4 -NPh) 2 (CO) n ],367 where the imido ligand caps a square metal face. The crystal structure of this cluster was not obtained, but the structure of the homonuclear analogue [Fe 4 (^4-NEt) 2 (CO) n ]367 confirms this bonding mode.…”

“…Shorter N-N bond distances (1.361-1.413 Å) are found in Fe 2 carbonyl complexes with this coordination mode. [51][52][53][54][55][56][57] These complexes are usually prepared from diazo compounds and apparently retain some diazo character. A Zr, 58 W, 33 and Sm 59,60 complex with this hydrazido(2-) bonding mode have also been reported.…”
