New molecular complexes of trimeric perfluoro-ortho-phenylene mercury with heterocyclic compounds

Slow evaporation in air of the solution of trimeric perfluoro-ortho-phenylene mercury (1) and 2,1,3-benzothiadiazole (2) in THF affords a complex l.2 (2)center dot H2O0.59 (3). A complex of 1 with di(tetrahydrofur-2-yl) ether (4; probably, a THF oxidation product) with a composition of 1.4 (2) (5) is detected as a minor admixture to 3. The structure of complexes 3 and 5 is determined by single crystal XRD. In complex 3, a molecule of 1 participates in HgaEuro broken vertical bar N and pi(F)aEuro broken vertical bar H-C interactions with one molecule of 2 and in the pi(F)aEuro broken vertical bar pi(H) stacking interaction with another. Complex 5 is formed by HgaEuro broken vertical bar O interactions with the participation of both heterocycles of a molecule of 4.
