A Polyfunctional Lewis Acid with Antifacial µ3-N,N-Dimethylformamide Ligands in [(o-HgC6F4)3(dmf)2]

Abstract

In [(o-HgC6F4)3(dmf)2], the cyclotrimeric tetrafluoro-o-phenylenemercury(II) molecule is ligated by two m3-dmf-O molecules above (Hg-O 2.837(7), 2.895(5), 3.036(5) �) and below (Hg-O 2.820(5), 2.863(6), 2.927(6) �) the Hg3 plane with the two oxygens and the three mercury atoms in a trigonal bipyramidal arrangement about the centroid of the Hg3 plane.
