The coordination chemistry of 6-chloro-2-(quinolin-2-yl)-2,4-dihydro-1H-benzo[d][1,3]oxazine (LH2) towards zinc and mercury has been explored. The ligand exhibits high versatility and provides different environments to the metal centre as a function of its diverse coordination modes. In one of the isolated and characterized complexes,...

Polyether adducts of d-block metal compounds as starting materials for new cluster compounds

Crochet, Aurélien ; Fromm, Katharina M.

In: Zeitschrift für anorganische und allgemeine Chemie, 2010, vol. 636, no. 8, p. 1484–1496

New crystalline cobalt, nickel, zinc, and mercury halide adducts with polyethers as ligands have been isolated, characterized, and identified as [Co(μ-Cl)₂CoCl₂(glyme)₂] (glyme = 1,2-dimethoxyethane), cis-[CoI₂(H₂O)₂(glyme)₂]²⁺[CoI₄]²⁻, [NiI₂(glyme)₂], [ZnI₂(glyme)], [HgCl₂(glyme)], [CoI₂(diglyme)] (diglyme = bis(2-methoxyethyl)ether), [ZnI₂(diglyme)],...

The compound N-(4-amino-1-methyl-5-nitroso-6-oxo-1,6-dihydropyrimidin-2-yl)-(s)-glutamic acid (H3L) was synthesised and structurally characterised by analytical methods and 1H, 13C and 15N NMR spectroscopy. This compound (H3L) shows the same topology as other model receptors previously used to develop chemical functionalization at the...
