A Polyfunctional Lewis Acid with Antifacial µ <i>3</i> - <i>N</i> , <i>N</i> -Dimethylformamide Ligands in [( <i>o</i> -HgC <i>6</i> F <i>4</i> ) <i>3</i> (dmf) <i>2</i> ]

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) Å) and below (Hg-O 2.820(5), 2.863(6), 2.927(6) Å) the Hg3 plane with the two oxygens and the three mercury atoms in a trigonal bipyramidal arrangement about the centroid of the Hg3 plane.
