the divalent chromium analogue. The reaction afforded in the case of both a and b the two nearly isostructural divalent complexes [CySCH2Si(CH3)2NSi(CH3)2CH2SCy]Cr(μ-Cl)}2 (4a) and [(t-Bu)SCH2Si(CH3)2NSi(CH3)2CH2S(t-Bu)]Cr(μ-Cl)}2 (4b) in crystalline form. To further clarify the interaction of 4 with aluminate species, we have carried out in situcomplexation in the presence of either AlCl3 or AlMe3

The preparation and characterization of the macrocyclic diamido-diarsine ligand [As2N2]Li2(1,4-dioxane) (1) (where As2N2 = PhAs(CH2SiMe2NSiMe2CH2)2AsPh) and a series of early transitionmetal complexes are presented. The complexes [As2N2]MCl2 (M = Zr, 2; Ti, 4) and the complex ([As2N2]Y)2(mu-Cl)2 (5) can be prepared by reaction of 1 with the corresponding THF adduct of the metal halide. The iodide

pincer ligands, [NSiMe2CH2(RIm)}2]– (R = tBu, iPr, Ph) featuring three different N‐heterocyclic carbenes and a disilylamido moiety is reported. Treatment of the lithium salt of [NSiMe2CH2(RIm)}2]– with CuIOTf afforded the corresponding copper complexes [NSiMe2CH2(RIm)}2]Cu in 41–56 % yield. X‐ray crystal structures of [NSiMe2CH2(RIm)}2]Cu show that they are monomeric and feature three‐coordinate, pseudo
