Lithium–nitrogen and lithium–boron–nitrogencage compounds formed using the phenylhydrazido backbone

Abstract

Two rare examples of the crystal structures of large molecular clusters formed from the lithium salts of multianions are reported; the first is the dilithium salt of phenylhydrazine, which forms a tetrameric cage with a core of eight Li and eight N centres; the second is a 32-membered cage which forms from the aggregation of two [B(NNPh)₃]⁶⁻ hexaanions, two [NH–NPh]²⁻ dianions and 16 Li⁺ cations.
