Stoichiometric assembly of [Sb(PCy)3]2Li6·6HNMe2·2C6H5Me; a highly fluxional antimony(III) phosphinidine complex containing Me2NH ligation of lithium†
Abstract
All of the Me2NH produced by the reaction of [Sb(NMe2)3] with CyP(H)Li (Cy = C6H11) coordinates the Li+ cations of the product [Sb(PCy)3]2Li6·6HNMe2·2C6H5Me 1; the complex contains the first example of a group 15 metal phosphinidine anion {[Sb(PR)3]3–}.
