“…Initial reactions to prepare Cu(I) phosphinimide complexes 1 and 2 focussed on the reaction of CuCl with either [LiNP (NMe 2 ) 3 ] 15 or [LiNPPh 3 ] 16 in THF (Scheme 1). The [LiNP(NR 2 ) 3 ] complexes were made in situ from n-butyllithium and HNP (NR 2 ) 3 .…”

The copper phosphinimide complexes [Cu{μ-N[double bond, length as m-dash]PR3}]4 (1, R = NMe2 and 2, R = Ph) were obtained in good yields from the reactions of Cu[Mes] (Mes = mesityl, C6H2Me3-2,4,6) with the corresponding iminophosphoranes, HNPR3. The molecular structures of 1 and 2 reveal the presence of planar eight-membered {Cu4N4} rings which contrasts with the saddle-shaped {M4N4} rings found in related metal phosphinimide complexes. According to computations, there is negligible aromaticity in the planar {Cu4N4} rings in 1 and 2 and the saddle shape observed in related {M4N4} rings is due to steric factors.

Die Alkalimetall‐Phosphaniminate MNPPh3 mit M = Na, K, Rb, Cs werden durch Reaktion von Ph3PI2 mit den Alkalimetallamiden in flüssigem Ammoniak hergestellt und durch Extraktion mit Toluol in reiner Form erhalten. Das Ethylderivat KNPEt3 wird analog hierzu aus Et3PBr2 hergestellt und mit Hexan in reiner Form extrahiert. Einkristalle der Phosphaniminate von Rubidium und Caesium werden aus Toluol bzw. Toluol/Hexan erhalten und durch Kristallstrukturanalysen charakterisiert. [RbNPPh3]6 · 41/2 Toluol (1): Raumgruppe P1, Z = 2, Gitterkonstanten bei 193 K: a = 1525,5(2); b = 1902,9(2); c = 2178,3(2) pm; α = 95,435(12)°; β = 91,145(12)°; γ = 90,448(12)°; R1 = 0,0529. Die Verbindung hat die Struktur eines Doppelwürfels, dessen N‐Atome der gemeinsamen Rb2N2‐Fläche trigonal‐bipyramidal von vier Rb‐Atomen und dem P‐Atom der (NPPh3–)‐Gruppe umgeben sind. [CsNPPh3]4 · 2 Toluol · 33/4 Hexan (2 a): Raumgruppe Fd3, Z = 8, Gitterkonstanten bei 123 K: a = b = c = 2679,7(1) pm; R1 = 0,0405. [CsNPPh3]4 · 2 Toluol (2 b): Raumgruppe P21/n, Z = 4, Gitterkonstanten bei 193 K: a = 1418,9(1); b = 2258,9(1); c = 2497,6(1) pm; β = 91,055(6)°; R1 = 0,0278. Beide Caesiumverbindungen bilden Cs4N4‐Heterokubangerüste, die sich durch ihre Packung und durch die Bindungswinkel an den Cs‐ und N‐Atomen unterscheiden.
