with sodium amide in DME as solvent. Like in the case of the lithium

A One‐Pot Synthesis of “K(hfa) glyme” Adducts: Effect of the Polyether Length on the Ion Coordination Sphere

“…[18][19][20] Potassium ion has a large ionic radius (r 6-coord = 1.51 Å), [13] which is responsible for interesting coordination moieties giving rise, in function of the coordinating ligands to extended oligomeric or polymeric network. [21][22][23] Former studies have shown that glymes play a crucial role in stabilizing complexes of alkaline-earth, [24][25][26][27][28] transition [29,30] and rare-earth metals [31,32] through oxygen-ion complexation. Recently, we have also devoted our attention to alkali metals, namely Li [33] and Na.…”

Formation and structural characterization of a potassium amidinoguanidinate

“…An increased tendency towards -coordination modes is characteristic for the heavier alkali metals and has frequently been observed in other complexes with nitrogen ligands (e.g. von Bü low et al., 2004;Liebing & Merzweiler, 2015). However, in potassium amidinates and guanidinates, a symmetric double-chelating coordination is usually preferred over coordination modes with a contribution of the -electron system (Fig.…”

Novel Copper(I) Clusters with 2‐(Diphenylphosphanyl)anilide Ligands. Synthesis and Crystal Structures of [Cu6X2(NHR)4] (X = Cl, Br, I; R = C6H4‐2‐PPh2)

“…In most cases the HL – ligand adopts a bidentate chelating coordination mode and in some rarer cases of di‐ or oligonuclear complexes μ 2 ‐(κP,κ 2 N) bridging HL – ligands have been observed. As part of our investigations on functionalized anilides we have been interested in the coordination behavior of the 2‐(diphenylphosphanyl)anilide (HL – ) towards copper(I). Generally, copper(I) amides and imides are well known for their structural diversity, which is mainly based on the ability to form oligomeric compounds with bridging N R 2 – and N R 2– ligands.…”
