Synthese und Festkörperstruktur eines Ga‐substituierten Distibens und eines Sb‐Analogons von Bicyclo[1.1.0]butan

Abstract: RGa {R = HC[C(Me)N(2,6-iPr 2 C 6 H 3 )] 2 }r eagiert mit Sb(NMe 2 ) 3 unter Insertion in die Sb-N-Bindung und der Eliminierung von RGa(NMe 2 ) 2 (2), gefolgt von der Bildung eines Ga-substituierten Distibens R(Me 2 N)GaSb = SbGa-(NMe 2 )R (1). Die Thermolyse von 1 verläuft unter Eliminierung von RGa und 2 und darauffolgend unter Bildung des Bicyclo[1.1.0]butan-Analogons [R(Me 2 N)Ga] 2 Sb 4 (3).Monovalente Verbindungen der 13. Gruppe, [ RM] x (M = Al, Ga, In, Tl), und metalloide Cluster [R x M y ]( x < y)s in… Show more

“…The central Sb–Sb bond lengths [ 1 : 2.6442(11) Å, 2 : 2.6310(5) Å, 3 : 2.6495(4) Å] are almost identical and agree very well with those of previously reported Ga‐substituted distibenes [L( X )GaSb] 2 [ X = Cl 2.6461(2) Å, NMeEt 2.6433(6) Å,[17b] NMe 2 2.6477(3) Å[17a]] and distibenes R Sb=Sb R containing sterically demanding organic substituents, for which values from 2.64 to 2.70 Å were reported . The Sb=Sb double bonds are shorter than Sb–Sb single bonds typically observed in distibines R 4 Sb 2 .…”

“…The 1 H NMR spectra of 1 – 3 in [D 6 ]benzene show two septets and four doublets for the magnetically inequivalent i Pr groups of the β‐diketiminate ligand and single resonances for the γ‐CH and the methyl groups of the C 3 N 2 M ring, whereas the 13 C NMR spectra of 1 – 3 each show 14 signals of the β‐diketiminate groups (Table ). Comparable findings were reported for dipnictenes of the general type [L(Cl)Ga E ] 2 ( E = As,[17c] Sb[17b]).…”
