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,...

Coordination Networks of Mercury(II) Halides and Polyether Ligand

Crochet, Aurélien ; Fromm, Katharina M.

In: Zeitschrift für anorganische und allgemeine Chemie, 2011, vol. 637, no. 14-15, p. 2089–2092

New crystalline mercury halide adducts with polyetheras ligands were isolated, characterized, and identified as trans-[HgIICl₂(diox)₂]n (1) and trans-[HgIII₂(diox)]n (2). The compounds were obtained from the metal halide salts in solution of 1,4-dioxane and can be considered as “cutting-out”...

Crochet, Aurélien ; Kottelat, Emmanuel ; Fleury, Antoine ; Neuburger, Markus ; Fromm, Katharina M.

In: Zeitschrift für anorganische und allgemeine Chemie, 2011, vol. 637, no. 6, p. 672–675

Dibenzo-24-crown-8 is studied herein as a flexible ligand able to adopt different conformations, as well as for the complexation of mercury. The recrystallization of dibenzo-24-crown-8 (DB24C8) from dry THF gives a new polymorphic structure of this ligand. This new structure is described and compared to the literature compound. Additionally, coordination of this ligand to mercury iodide HgI₂ is...

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)],...
