Does H3O+ Really Act as a Ligand in the Solid State?

“…There is a literature precedent for intramolecular H-bonding between the O atom of an aqua ligand and a cationic protonated N atom ( GUKRAF ; d O–N = 2.842 Å: HIHTUP ; d O–N = 2.865 Å: VINKOT : d O–N = 2.941 Å: and VINKUZ ; d O–N = 2.924 Å), and these structures are consistent with the coordinated H 2 O ligand being feebly basic.…”

New bridging ligands from methylation reactions of μ-vinyliminium diiron complexes

“…Apart from any attempt to determine the more appropriate description, the nature of the bridging ligand appears very unusual and interesting. Coordination of vinylammonium ligands has been described only for mononuclear complexes [11], and oxidative addition of vinylammonium salts to Ni complexes has been reported [12]. The latter reaction leads to C-N bond cleavage and generates amine and allyl ligands.…”

Olefin-Copper(I) Complexes and their Properties

“…We [87] have found that ([VB-N-CIN]Cl) and 4-vinylbenzyl chloride in refluxing acetone and N,Ndimethylformamide (equation (20), figure 21a), solvothermally react with CuCI to form an unprecedented 2-D layered homochiral copper(I)-olefin coordination polymer of formula, Cu 5 C1 6 (VB-N-CIN) 2 C 2 H 5 OH (1EtOH) (equation (21) figure 21b). It is noteworthy that two adjacent layers are in an AA type arrangement …”

“…Ferroelectric properties [91,92] The reactions of quinine with CuCl and CuBr afford Cu 8 Cl 10 (HQuinine) 2 (1) and Cu 8 Br 10 (HQuinine) 2 (2) (figure 29), respectively. The 2-D layer networks are (20) isostructural (equation (26)). The space group C2 is associated with the point group C 2 , one of the 10 polar point groups (C 1 , C s , C 2 , C 2v , C 3 , C 3v , C 4 , C 4v , C 6 , C 6v ) required for ferroelectric behavior.…”
