(μ2-2-Methoxyethanol-κ3O1:O1,O3)(2-methoxyethanol-κO1)tris(μ2-3,4,5,6-tetrafluoro-o-phenylene-κ2C1:C2)trimercury(II)

Abstract

In the title compound, [Hg3(C6F4)3(C3H8O2)2], two O atoms from one 2-methoxyethanol ligand and one O atom from the second 2-methoxyethanol ligand coordinate three HgII atoms [Hg—O = 2.765 (7)–2.890 (8) Å] in the trimeric organomercurial Lewis acid (o-C6F4Hg)3. The hydroxy groups are involved in formation of intra- and intermolecular O—H...O hydrogen bonds; the latter link two molecules into centrosymmetric dimers. An extensive net of weak intermolecular C—H...F interactions further consolidates the crystal packing.
