Kristallstruktur des Zinkamids Zn[N(SiMe3)2]2

Abstract: X-ray quality crystals of Zn[N(SiMe 3 ) 2 ] 2 (monoclinic, P2 1 /c) are obtained by sublimation of the zinc amide Zn[N(SiMe 3 ) 2 ] 2 at Ϫ30°C in vacuo (300 torr). According to the result of the X-ray Nachdem bereits 1849 Diethylzink und wenig später die erste Zink-Stickstoffverbindung durch Frankland [1] synthetisiert wurden, gelang es erst mehr als 100 Jahre danach, 1983, erstmals ein molekulares Zinkamid strukturell zu charakterisieren [2]. In der Folgezeit wurden Zinkamide mit den Strukturen 1-6 bekannt ge… Show more

“…Brought to you by | University of Bath Authenticated Download Date | 6/8/15 3:26 PMshow the formation of a delocalized π -electron system within the NCN unit of the amidinate ligand. The Zn-N amide bond length is signifi cantly shorter compared to the Zn-N amidinate bonds, but agrees well with the values observed byMargraf et al (2004) for Zn[N(SiMe 3 ) 2 ] 2 [1.833(11) Å ] and other zinc bis(trimethylsilyl)amides as revealed by a Cambridge structural database (CSD) search. The CSD search gave 75 complexes containing a Zn-N(SiMe 3 ) 2 bond.…”

“…In 1 the Zn–N bonds to the bis(trimethylsilyl)amide anions show the smallest values due to a rather large electrostatic attraction. Nevertheless, in Zn[N(SiMe 3 ) 2 ] 2 with a dicoordinate zinc atom significantly smaller Zn–N bond lengths are observed (Zn–N, solid state: 183.3(11) pm 10, gas phase: 182.4(14) pm 11). The influence of the coordination numbers of zinc and nitrogen on the Zn–N distances is nicely shown for a number of homoleptic zinc amides of the type Zn[N(Si R 3 ) R ′] 2 12 and Zn(NPh 2 ) 2 13.…”

“…Im Jahre 1965 wurde die Synthese von Zn[N(SiMe 3 ) 2 ] 2 erstmals von Wannagat und Mitarbeitern beschrieben [3]. Die Kristallstruktur zeigt als zentrales Strukturelement dieses monomeren Zinkamids eine nahezu lineare N-Zn-N-Einheit [4]. Monomere Molkülstrukturen weisen neben dem erwähnten Zinkamid auch die Komplexe M[N(SiMe 3 ) 2 ] 3 der dreiwertigen Metalle ( M = Cr, Mn, Fe, Co) auf [5 -7].…”
