Syntheses and crystal structures of the monomeric bora-amidinate (bam) complexes DIPPNBN-Mg·(THF)3 and DIPPNBN-Ca·(THF)4 are presented; DIPPNBN = HB[N(2,6-iPr2-C6H3)]2. The simplicity of their 1H NMR spectra in THF-d8 suggest that their monomeric s

Reaction of the diprotic ligand [Xanthdim]H(2) (a ligand system where two adjacent beta-dialdimine units are linked by a xanthyl backbone) with 2 equiv of potassium hydride or benzylcesium gave access to bimetallic alkali metal complexes. These compl

The diprotic bis(salicylaldimine) ligand N,N′-bis(3,5-di-tBu-salicylidene)diimine, (1-NN)H2, was smoothly deprotonated by reaction with two equivalents of a metal amide M[N(SiMe3)2]2 (M = Mg, Ca or Zn) to form a bimetallic metal amide complex (1-NN

A series of dinucleating bis(β-diketiminate) ligands with rigid bridges has been prepared. In all cases the β-diketiminate unit is 2,6-iPr2C6H3NC(Me)C(H)C(Me)N-(bridge), and the bridges are either para-phenylene, meta-phenylene or 2, 6-pyridylene (
