✦ Synopsis

The interaction of trimeric perfluoro-ortho-phenylene mercury (1) with bis(2-hydroxyethyl)sulfide (S((CH 2 ) 2 OH) 2 ) in dichloromethane and methylparathion (SP(OMe)

, respectively. These two adducts have been characterized by elemental analysis and single crystal X-ray diffraction. The structure of [1 • S((CH 2 ) 2 OH) 2 ] shows that the bis(2-hydroxyethyl)sulfide molecule interacts with the mercury centers of 1 by formation of a Hg-S interaction of 3.138(4) Å. Association of the two components is further strengthened by the coordination of one of the oxygen atoms of the bis(2-hydroxyethyl)sulfide molecule. This oxygen atom interacts simultaneously with three mercury centers of 1 with Hg-O distances ranging from 2.889(8) to 3.142(9) Å. In the lattice, molecules of [1 • (S((CH 2 ) 2 OH) 2 )] associate with compact cofacial dimers with Hg-Hg metallophilic contacts of 3.794 Å and 4.076 Å. The structure of [1

is that of a 2:1 complex in which two molecules of methylparathion are triply coordinated via their sulfur atom to the mercury centers of 1 on either side of the molecular plane. The Hg-S contacts fall within the range of 3.
