Synthesis of a deca-lithium cage containing an [(RN)2As(μ-NR)As(NR)2]4− tetraanion; a homologue of group 15 trianions of the type [E(NR)3]3−†
Abstract
The novel, deca-lithium cage [{mtaNHLi}{As2(Nmta)5}Li4·2thf]2 (1) (mtaN= 5-methylthiazolyl, C4H4N2S) contains an imido-bridged tetraanion [(mtaN)2As(μ-Nmta)As(Nmta)2]4−, which represents a new type of multifunctional imido group 15 ligand framework (homologous with group 15 anions of the type [As(NR)3]3−).
